A VSC Controller with Silding Mode Design Based on H\- Theory

为避免未建模误差对系统性能的影响，采用滑模面的频域整形方法提出了一种基于Ｈ∞理论设计滑模面的变结构控制器，并将其运用到一泵控马达伺服系统中。仿真结果表明这种控制器对建模误差有很强的鲁棒性。

In order to attenuate the influence of systems unmodeled errors,this paper adopts frequency shaping design method to sliding mode,and a new VSC controller based on H\- theory is proposed.The controller is used in a pump control motor system,the simulation results show it is robust to the unmodeled errors.\;
