基于回路成形法的鲁棒控制器设计

Design of robust controller based on loopshaping

在对信号和系统范数以及鲁棒性描述的基础上介绍一种鲁棒控制器的图形设计方法──回路成形法，它能有效地解决被控对象的不确定性和外部干扰问题．最后，针对一设计实例用 Ｍａｔｌａｂ的动态仿真工具 Ｓｉｍｕｌｉｎｋ对设计出来的控制器进行系统仿真，成功地验证了回路成形法的有效性．

Based on a description of signal and system norm and of robust performance, this paper introduces loopshaping, a graphic design method for robust controller which can overcome effectively the uncertainty of the controlled object as well as external distraction. The effectiveness of loopshaping is succesfully testfied by systematic simulation of a controller designed by Simulink (the dynamic simulative tool of Matlab).
