零相位跟踪控制的交流位置伺服系统研究

Zero Phase Error Tracking Control for AC Position Servo control System

本文针对位置伺服系统中存在的跟踪误差，研究了零相位跟踪控制的交流位置伺服系统，提出了一种简便易行的设计零相位跟踪控制器的方法—扩展频带零相位跟踪控制。仿真和实验结果表明，采用零相位跟踪控制器来减小位置伺服系统的跟踪误差是十分有效的。

To decrease the tracking error in AC position servo control system,a novel design approach of zero phase error tracking controller(ZPETC)is proposed,which is called Extended Bandwidth Zero Phase Error Tracking Control(EBZPETC).Simulated and experimental results show that the proposed method is effective for decreasing the tracking error.
