摘　　要：　介绍了一种二自由度H∞控制器的设计,这种二自由度H∞控制器一方面可使控制系统获得良好的参考信号的跟踪性能,同时还可消除频率随时间变化缓慢的准-周期信号的干扰.Description is done to the design of a H\-∞ controller with two-degree-of-freedom. The aim is to obtain, on the one hand, good reference tracking properties and, on the other hand, to reject quasi-periodic disturbance in the control system. It is applied in a web transport system, its abilities of tracking and rejection of quasi-periodic are validated with simulations.

关 键 词：二自由度H∞控制器 准-周期干扰信号 消除方法 工业控制系统 权重函数
