重复控制在光电跟踪伺服系统中的应用

在光电跟踪系统中,伺服系统的跟踪精度决定了其捕获跟踪能力。随着光电跟踪伺服系统对跟踪精度的要求逐步提高,将重复控制技术引入到伺服系统中。重复控制不仅能够实现高精度跟踪、改善系统性能,而且可以跟踪周期性信号。设计了优化插入式重复控制器,并对等效正弦信号进行跟踪。与常用高精度控制方法进行仿真比较,其结果表明,重复控制系统的跟踪误差明显减小,其跟踪精度得到明显提高。

Research on Repetitive Control in Optoelectronic Tracking Servo System

In the photoelectronic tracking system, The ability to capture and trace is determined by the tracking precision of servo system. As the photoelectric tracking servo system gradually rise to the requirement of tracking precision, repetitive control technology is introduced into the servo system in this article, repetitive control technology not only can realize high-precision tracking, improve system performance, and can track the periodic signal. In this paper, optimization of plug-in repetitive controller was designed, to track the equivalent sine signal, the simulation results show that the tracking error of repetitive control system is obviously decreased, and its tracking accuracy is improved obviously compared with commonly used high precision control method.
