Zero Phase Error Tracking Control with Variable Gain for AC Positional Servo Control System

针对交流位置伺服系统中零相位跟踪控制器对建模误差、系统参数变化相当敏感的缺点，提出了一种简单有效的设计零相位跟踪控制器的方法──变增益零相位跟踪控制，仿真结果表明，采用这种零相位跟踪控制器来减少位置伺服系统的跟踪误差是十分有效的．

To overcome the drawbacks of the zero phase error tracking controller (ZPETC) which is sensitive to modeling error and parameter variations in the AC positional servo control system, an improvement in the controller design, the 'Zero Phase Error Tracking Controller with Variable Gain',is proposed. Computer simulation results show that the design improvement proposed is simple and effective.
