"Modeling and Control of Hysteresis Nonlinearities in Smart Actuators"

Prof. Chun-Yi Su, Concordia University, Canada

Abstract: Hysteresis nonlinearities are very common in magnetic materials, smart materials and industrial systems. For decades, the existence of such nonlinearities have provided one of the most difficult challenges to control design engineers since the entire Laplace domain and most state space control design techniques were developed exclusively for differentiable linear or nonlinear systems. Hence, the existence of hysteresis nonlinearities in smart material based actuators and systems were neglected and the controllers were designed based on the nominal smooth systems. When the systems are considered with non-differentiable nonlinearities, these methods encountered substantial difficulties in the analysis, model fitting and control design stages. It was extremely difficult, if not impossible, to design or prove stability of such systems. The development of techniques for the identification of such nonlinearities in realistic industrial plants has emerged as a significant problem in itself. This talk is intended to raise awareness of modeling and control techniques and to provide an opportunity to discuss state-of-the-art solutions for the problems. The presentation and discussion will range from modeling of hysteresis, to the design of corresponding control schemes, especially in the absence of complete information concerning the system model and state.

"Smart City Infrastructure: Energy Management and Environment Monitoring"

Assoc. Prof. Quang Ha, University of Technology Sydney, Australia

Abstract: Smart cities are emerging as a solution to global problems associated with rapid urbanisation. The sustainable management of energy, air quality, materials and services in complex and evolving urban areas, including megacities, is essential to provide a healthy living environment for the city's inhabitants. To better understand the energy functioning and health of urban environments, this keynote outlines the integration of sensor data measures in order to optimise their synergies for developing a digital virtual city model amenable to real-time and interactive management and decision making. By combining smart sensors, satellite sensing and distributed control with The Internet of Things, not only can we effectively improve energy efficiency via integration diverse energy sources into electricity grid, but also significantly reduce emissions and monitor their complex interactions in time and space. This will contribute towards new, meaningful and useful urban-intelligence.

About: Quang Ha received the B.E. degree from Ho Chi Minh City University of Technology, Vietnam, in 1983, the Ph.D. degree from Moscow Power Engineering Institute, Russia, in 1993, and the Ph.D. degree from the University of Tasmania, Australia, in 1997, all in electrical engineering.

"Covering Method in Stability Analysis and Controller Design of Switched Systems with Delays"

Prof. Xingwen Liu, Southwest Minzu University, China

Abstract: Stability analysis and controller design are fundamental tasks in control theory. The most popular tool fulfilling such tasks is Lyapunov method. However, this method generally cannot achieve the desired results when delayed switched systems are considered. On this ground, alternative non-Lyapunov method, covering approach, is proposed to surmount the difficulties faced by Lyapunov method. The core lies in: By constructing a covering which covers the trajectories of switched systems starting from a specified region, the stability conclusion follows from the convergence to zero of the covering. With this framework, we can easily handle the problems of robust converge of nonlinear switched systems with delays and perturbations, stability and controller design of switched positive systems with unbounded delays, and stability and controller design of cascade switched nonlinear systems with bounded delays.
