摘要

这封信介绍了一种改进的重复控制器（IRC），它使用复杂系数滤波器来增强系统对周期信号的跟踪性能。与传统重复控制器（CRC）中使用的低通滤波器相比，当两个滤波器具有相同的截止频率时，在周期信号的频率处，特别是在基频处，复系数滤波器使信号的相位和幅度变化较小。因此，基于irc的控制系统比基于crc的控制系统具有更好的跟踪性能。一个旋转控制系统的仿真结果证明了IRC的优越性。

An Improved Repetitive-Control System Using a Complex-Coefficient Filter

Dear Editor, This letter presents an improved repetitive controller (IRC) that uses a complex-coefficient filter to enhance the tracking performance of a system for periodic signals. Compared with the low-pass filter used in the conventional repetitive controller (CRC), the complex-coefficient filter causes less change in the phase and amplitude of a signal at the frequencies of the periodic signal, especially at the fundamental frequency, when the two filters have the same cutoff-frequency. Thus, the IRC-based control system has better tracking performance than the CRC-based control system. Simulation results of a rotational control system demonstrate the superiority of the IRC.
