This method acquires good performance of disturbance restraining and robust stability by revising frequency characteristic of sensitivity function. It receives better compensating effect than directly robust control.
针对直接鲁棒控制动态性能差的缺点,提出一种基于混合灵敏度设计的H∞控制方法,从干扰抑制的角度出发,通过对灵敏度函数频率特性的整形,达到兼顾系统干扰抑制性能与鲁棒稳定性的目的,从仿真结果上看,该方法能够实现对控制目标的跟踪,补偿性能优于直接鲁棒控制。
