Employing Nonlinear Benefits in Engineering: Theory and Methods
Prof. Xingjian Jing, Department of Mechanical Engineering, Hong Kong Polytechnic University
Abstract: Employing nonlinearity in engineering applications is a challenging but very promising topic in the literature in recent years. Nonlinearity can be employed in various vibration control, energy harvesting and structure health monitoring for achieving advantageous performance. A special issue on this topic will be published on the leading journal – Mechanical Systems and Signal Processing. This talk will focus on a brief introduction of a theory for nonlinear analysis and design in the frequency domain with several new concepts such as nonlinear characteristic output spectrum (nCOS) or nonlinear output frequency response function (NOFRF). This method can present a novel and powerful insight into understanding nonlinear dynamics, developed in recent years. Following this, some R&D activities will be introduced about a class of bio-inspired anti-vibration structures and their applications in passive vibration control, energy harvesting systems, fault detection and diagnosis and robotics etc, recently investigated in HK PolyU.

Research Advice for Graduate Students
Professor Ryan Loxton, BSc (Hons), PhD, FAustMS, FORS || School of Electrical Engineering, Computing, and Mathematical Sciences || Curtin University, Australia
Time and classroom is to be announced.
Abstract: Graduate students face the daunting task of transitioning from “learner” to “inventor” and this requires much more than just technical knowledge – for example, the ability to write and communicate is crucial, but such “soft skills” are often neglected in the education system. This talk aims to address this gap by providing graduate students with advice on improving academic writing and building a long-term research career. The speaker will discuss such questions as: “How to choose a research direction?”, “How to do high-quality research?” and “How to write publications?”. The talk is based on the speaker’s personal experience as a senior researcher who has worked with many graduate students in China.

- Soft Robot made of hydrogel and electroactive polymer, by Tiefeng Li（李铁风）
Abstract: The softness and large strain actuation of responsive hydrogels promise the potential to fabricate soft devices, which can function as a robotic system. The key challenges lie in the fabrication of soft devices with robust actuating ability and biocompatibility to the attached organ. Here we present a solution that integrates the responsive hydrogel membrane, electro-active polymer and flexible electronics can be integrated into a electromechanical device. As an example, the actuation assisting function of this soft device for shrinking an animal bladder is presented. The mechanical behaviors of the balloon-like soft device are experimentally and theoretically investigated. The concepts are applicable to other applications such as soft implants, soft robotics, and microfluidics.
- Biologically Inspired Robots: Flying Like a Fly, Swimming Like a …. Fly?, by Pakpong Chirarattananon, Assistant Professor, Department of Biomedical Engineering City University of Hong Kong (Email: firstname.lastname@example.org; Web: http://ris.mbe.cityu.edu.hk)
Abstract: Using only tiny nervous system, flying insects are able to perform superlative aerodynamic feats such as deftly avoiding a striking hand or landing on flowers buffeted by wind. These amazing creatures inspire scientists and engineers to understand and translate this ubiquitous form of locomotion into man-made machines. In this talk, I will discuss challenges that arise in the fabrication and control and exciting research outcomes related to millimeter-scale biologically-inspired flapping-wing robots. Challenges for the development of such small robots are associated to actuation, power and complex fluid-structure interactions. Through multiple iterations of designs, experiments and theoretical modeling, over the years, not only did we demonstrate a stable tethered flight of an insect-scale robot, but complex maneuvers have also been realized. The flapping-wing robot is capable of flying, landing on a wall, or swimming and transitioning out of the water.
Biography: Pakpong Chirarattananon received his Bachelor and Master degrees from University of Cambridge, UK, and a Ph.D. degree from Harvard University under the supervision of Professor Robert Wood in 2014. His graduate work was centred on the dynamics and control for insect-scale flapping-wing robots. In December 2014, he joined the Department of Mechanical and Biomedical Engineering as an Assistant Professor and founded the Robotic and Intelligent Systems Laboratory at City University of Hong Kong. Dr Chirarattananon is broadly interested in applying control and dynamic system theories to study aerial and biologically-inspired robotic systems. He has published in Science, Science Robotics, and has been nominated as the best student paper award finalist at the 2013 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) and the best paper award finalist at the 2014 IEEE International Conference on Biomedical Robotics and Biomechatronics.

- Stochastic Hydrodynamic Model for Biogenic Mixing, by Zhi Lin 林智
Abstract: Biogenic mixing (the mixing and transport due to the swimming of marine species) has attracted a significant amount of interdisciplinary research efforts in recent years. In previous work, the applicant has contributed in deriving a stochastic hydrodynamic model that incorporates both deterministic fluid dynamics models and statistic description for stochastic swimming with a bottom-up approach and leads to a formula for the effective diffusivity. This model provides a new approach for the study of biogenic mixing and similar phenomena in other areas of science and engineering. Recently, we are seeking to improve the model and its simulation by considering various complicated factors, such as anisotropic swimming, nonlinear coupling by massive schooling.

- Living Cell based Modular Micro Robot Fabricated by Robotic Micro-Manipulation System, by Lianqing Liu 刘连庆 (Professor Shenyang Institute of Automation, Chinese Academy of Science, China)
Abstract: Micro-robots have a great application prospect in the biomedical field due to the feature of small size. To solve the issues of energy supply and bio-compatibility of micro-robots, the bio-syncretic micro-robots actuated by living cells have been studied widely. However, the fabrication, assembling and control of the bio-syncretic micro-robots are the main challenges for the development of the bio-syncretic micro-robots. In this talk, manufacture and control of the living cells based modular micro robots will be discussed. Firstly, a robotic micro-manipulation system will be introduced to implement the high-throughput fabrication of the biological modules of micro robots, and to execute the on-line flexible assembling of the bio-syncretic robots by the fabricated living cells based modules. Then, an approach based on circularly distributed multiple electrodes (CE) will be induced to improve the differentiation of myoblast cells and characterize the electro-responsive beating behavior of living myotubes for the development of bio-syncretic micro robots. Moreover, a biomimetic bio-syncretic crawler actuated by living myotubes was demonstrated to move under the control of the CE. This talk will not only be related to the micro-robots, but will be also informative for biological tissue engineering and drugs screening.

- Flow visualization and measurement via computer vision technologies, by Shengze Cai 蔡声泽
Abstract: Particle image velocimetry (PIV), as a flow visualization technology, can provide non-intrusive quantitative measurement of the velocity fields. This technique has been studied intensively and plays an increasingly important role in experimental fluid mechanics. To go deeper insight into complex flow phenomena, precise motion estimation methods dedicated to fluid mechanics and towards real-time measurement are being investigated in this talk. On the one hand, variational optical flow computation coupled with the stochastic transport theory is proposed for turbulent flow estimation. This formulation can extract accurate velocity fields from particle images as well as scalar images. On the other hand, deep learning technique is also introduced to PIV estimation with high efficiency, which is promising for real-time measurement and active flow control.
Title: Security in Cyber-Physical Systems: A Control Systems Perspective
演讲人：Prof. Petros Voulgaris, UIUC, Fellow of IEEE
Cyber-physical systems (CPS) have become ubiquitous in engineering and have extended the range of aerospace applications to several new domains. Unmanned Arial Vehicles (UAV) are typical examples of CPS that can execute cooperative missions of increasing complexity without constant supervision of human operators e.g., military reconnaissance and strike operations, border patrol missions, forest fire detection, police surveillance, and recovery operations to name a few. Similarly, current and future space applications such as satellite swarms and distributed spacecraft systems, autonomous and aerospace robotic systems, depend critically on the synergy of cyberspace with the physical components.
Pertinent to CPS is the notion of security, which is of paramount importance in aerospace, power, transportation, manufacturing, etc. The concept of security to malicious attacks brings an important new dimension in the design CPS. In this talk, we present some aspects of this problem related to control system security to attacks and provide some ways to enhance detection and awareness. More specifically, we elaborate on this issue from the control analysis, design and actual implementation point of view. We consider malicious attacks on actuators and sensors of a feedback system which can be modelled as additive, possibly unbounded, disturbances at the digital (cyber) part of the feedback loop. It is shown that the standard sampled data implementation can create additional vulnerabilities to stealthy attacks, and therefore, when security is at stake, it is of paramount importance to have methods to eliminate these vulnerabilities. By devising a multi-rate scheme we can guarantee that stealthy attacks are not possible. Further, we can provide precise trade-offs on performance and safety cost. Finally, we touch upon other type of attacks and their connections to switching systems and linear programming.
Professor Petros G. Voulgaris received the Diploma in Mechanical Engineering from the National Technical University, Athens, Greece, in 1986, and the S.M. and Ph.D. degrees in Aeronautics and Astronautics from the Massachusetts Institute of Technology in 1988 and 1991, respectively. Since 1991, he has been with the Department of Aerospace Engineering, University of Illinois where he is currently a Professor (also appointments with the Coordinated Science Laboratory, and the department of Electrical and Computer Engineering.) His research interests include optimal, robust and distributed control and estimation; networked control; applications of advanced control methods to engineering practice including, power systems, air-vehicle, nano-scale, robotic, and structural control systems. Dr. Voulgaris is a recipient of several awards including the NSF Research Initiation Award, the ONR Young Investigator Award and the UIUC Xerox Award for research. He has also been a Visiting ADGAS Chair Professor, Mechanical Engineering, Petroleum Institute, Abu Dhabi, UAE (2008-10).

Title: Machine learning via Wasserstein statistical manifold
Abstract: In this talk, I start with reviewing several primal-dual structures in optimal transport (Wasserstein metric). Based on it, I will introduce the Wasserstein natural gradient in parametric statistical models. We pull back the L2-Wasserstein metric tensor in probability density space to parameter space, under which the parameter space become a Riemannian manifold. The gradient and Hamiltonian flows in parameter space are derived. When parameterized densities lie in 1D, we show that the induced metric tensor and gradient flow establish explicit formulas. Examples are presented to demonstrate its effectiveness in several machine learning problems.
浙江大学玉泉校区智能系统与控制研究所二楼资料室, 9 a.m., July 2, 2018
Prof. Ryan Loxton, full professor in the School of Electrical Engineering, Computing, and Mathematics at Curtin University, Australia.
Abstract: Switched systems operate by switching among various different modes. Determining the optimal times at which the mode switches should occur is a fundamental problem in systems and control, with particular importance to the numerical solution of optimal control problems. This talk will discuss the switching time optimization problem for two classes of switched systems: those with time-dependent switching conditions (where the switches are directly controllable), and those with state-dependent switching conditions (where the switches occur when the system hits certain switching surfaces in the state space). It is widely believed that standard numerical optimization techniques struggle when applied to switching time optimization problems. In this talk we present new results showing that this challenge is over-stated; contrary to popular belief, switching times can in fact be optimized effectively using standard optimization methods. We verify this with a numerical example involving a switched system model for the production of 1,3-propanediol, an industrial polymer used in paints, adhesives, and lubricants.
