摘　　要：针对交流伺服控制器PI参数自整定方法中,忽略了整定过程的周期性和所需的自学习能力,造成整定过程效率低、重复操作次数多、整定时间长问题,依据迭代学习控制,提出了一种交流伺服系统速度控制器PI参数自整定控制方案,使控制器能够进行仿人操作,根据历史控制经验不断地改进学习增益。仿真和实验结果均验证了方案的有效性,且结构简单,易于实现。At present, most methods of self - tuning of PI controller for AC Servo drive cause various problems, such as low efficiency, more iterative manipulation and more setting time, due to ignoring the periodic property and the necessary self- study ability of setting process. This paper presents a novel on - line self - tuning of PI speed controller for AC Servo drive based on iterate learning control （ILC）. The proposed scheme make the controller improve learning gain according to historical experiences like human being. The feasibility and validity of the proposed scheme has been verified with simulation and experimental result and the arithmetic is concise and apt to realize.
