2010年秋季先进机器人与MEMS技术系列学术讲座（35）
南开大学机器人与信息自动化研究所 Institute of Robotics and Automatic Information System 2010年秋季先进机器人与MEMS技术系列学术讲座 Seminar Series：Advanced Robotics & MEMS 报告人：陈新开 教授 报告人单位：日本芝浦工业大学 题目： High precision control for piezo-actuated nano-positioner 地点：机器人所一楼资料室 时间：12月17日（周五）下午3：30~5:00； Abstract The nano-positioner is composed of a piezo electric actuator (PEA) and a positioning mechanism (PM). Due to the existence of hysteretic nonlinearity in the PEA and the friction in the PM, the high precision control of the piezo-actuated positioner is a challenging task. This research discusses the high precision control for the piezo-actuated stage by using the adaptive method. The proposed control law ensures the global stability of the controlled positioner, and the position error can be controlled to approach to zero asymptotically. Experimental results show the effectiveness of the proposed method. Biography Xinkai Chen received his Ph.D. degree in engineering from Nagoya University, Japan, in 1999. He is currently a full professor in the Department of Electronic and Information Systems, Shibaura Institute of Technology, Japan. His research interests include adaptive control, motion control and machine vision. Dr. Chen is serving on the editorial boards of several journals, including IEEE Transactions on Automatic Control, International Journal of Advanced Mechatronic Systems, etc. He has also severed as an organizing committee member for many conferences. |
