二自由度控制的鲁棒伺服系统

The Robust Servo System with Two Freedom Controlled

通常的—自由度控制的伺服系统,在谋求较好的跟踪特性的情况下,不能兼顾具有良好的反馈特性,因而当存在控制对象的模型化误差或参数变化时,其跟踪特性变得很差,以致不能正常工作。本文采用(?)自由度控制理论设计了鲁棒伺服系统。这种系统由于可独立设计跟踪特性和反馈特性,可同时具有良好的跟踪特性和反馈特性,因而当控制对象的参数大范围变化时,仍具有良好的跟踪特性。

The objective of this paper is to design a robust servo system using method of two freedom. This servo system can be designed for tracking character and feedback character independently. It has good tracking character when the parameter of the rontrol object is variable in large range.
