Prof. Chun-Yi Su, Concordia University, Canada Dr. Su received his B.E. degree in control engineering from Shaanxi Institute of Mechanical Engineering (now Xi'an University of Technology) in 1982, his M.S. and Ph.D. degrees in control engineering from South China University of Technology, China, in 1987 and 1990, respectively. His Ph.D. study was jointly directed at Hong Kong Polytechnic (now The Hong Kong Polytechnic University), Hong Kong. After long stint at the University of Victoria (1991-1998, Canada), he joined the Concordia University (Canada) in 1998, where he is currently Concordia Research Chair in Control and Professor of Mechanical Engineering. He has also held several short-time visiting positions in Japan, Singapore, China and New Zealand. Dr. Su's research covers control theory and its applications to various mechanical systems. His current main research interests are in control techniques for smart material based actuators, robotic and mechatronic systems, vehicle suspension and vibration, and nonlinear control systems. He is the author or co-author of over 180 publications, which have appeared in journals, as book chapters and in conference proceedings. Dr. Su is an Associate Editor of IEEE Transactions on Control Systems Technology, IEEE Transactions on Automatic Control, and Journal of Control Theory & Applications. He is on the Editorial Advisory Board of Mechatronics and on the Editorial Board of International Journal of Intelligent Systems Technologies and Applications. He has served on the technical program committee of numerous conferences in the area of control and automation. He has served as committee chairs of a number of these conferences, including the Program Chair of IEEE CCA07. Speech Title: Modeling and Control of Hysteresis Nonlinearities in Smart Actuators: Magnetostrictive Actuator Case Abstract: Magnetostrictive actuators featuring high energy densities, large strokes and fast responses are playing an increasingly important role in micro/nano-positioning applications. However, such actuators with different input frequencies and mechanical loads exhibit complex dynamics and hysteretic behaviors, posing a great challenge on applications of the actuators. To this end, a comprehensive model is developed. According to the proposed hysteresis model, an inverse Asymmetric Shifted Prandtl-Ishlinskii (ASPI) Model is proposed for the purpose of compensating the hysteresis effect. However, in real systems, there always exists a modeling error between the hysteresis model and the true hysteresis. The use of an estimated hysteresis model in deriving the inverse compensator would yield some degree of hysteresis compensation error. To accommodate such a compensation error, an analytical expression of the inverse compensation error is derived first. Then, a prescribed adaptive control method is developed to suppress the compensation error and simultaneously guaranteeing global stability of the closed loop system with a prescribed transient and steady-state performance of the tracking error. The effectiveness of the proposed control scheme is validated on the magnetostrictive- actuated experimental platform.
