报告题目：A New Design Approach of Higher Order Discrete Repetitive Control

内容简介：Repetitive control (RC) is well known as a method for tracking a periodic command as well as eliminating the influence of a periodic disturbance. An issue that can be encountered in applications is that the period of the disturbance can vary. In some cases one can monitor a drift in the disturbance period, but in other cases the period can fluctuate sufficiently fast that one wants an RC law that is robust to period fluctuations. Several studies address this problem using higher order RC incorporating a negative weight on errors from some previous period. This paper presents a systematic design procedure that can be used to improve RC robustness to disturbance period fluctuations. Methods are given to present the information needed to make the necessary tradeoffs when tuning the set of design parameters.

报告人简历：Hai-Jiao Guo received the BSc degrees in Physical department from Shanghai Normal University in 1982, the MS and the Ph.D. degree in electrical engineering from the Tohoku University, Japan, in 1988 and 1993, respectively. He was an Assistant Professor with the Department of Electrical Engineering, Tohoku University, Japan, from 1990 to 1996, and Assistant Professor from 1996 to 2004. Since 2004, he has been with the Dept. of Elect. &Infom. Engng, Tohoku Gakuin University, Japan, where he is currently a professor. He served as the chairman of the department from April 2014 to March 2016. His research areas include in robust design of digital servo system, and its application in the power electronics field, such as high performance drive of motors and inverter/converter.
