摘要
采用重复控制,可以显著提高控制系统对周期性信号的跟踪精度,提高系统的鲁棒性.针对反射镜高速摆动扫描系统,设计了基于重复学习控制补偿的控制器,通过对扫描系统常规PD控制与重复学习补偿控制的仿真对比,对50Hz参考输入周期扫描信号,所设计的重复学习控制系统能够高精度地跟踪给定周期信号.
Repetitive Learning control can efficiently improve the tracking performance of periodic signals for servo-system. A compensation controller was designed for fast scanning servo-system based on repetitive control scheme. In compare with general PD controller, the designed repetitive compensation controller can track the given periodic position signal of 50Hz with high accuracy.
