滑模变结构控制理论在电力电子电路的应用

Application of Sliding Mode Variable Structure Control on Power Electronic Circuit

针对BUCK变换器的传统设计方法的不足,利用滑模变结构控制理论设计BUCK变换器,探讨以期望输出电压为依据的切换面设计问题,并对BUCK电路滑动模态上的动态品质进行分析,具有较强的鲁棒性,此方法同样适用其它电力电子电路.

This paper provides a design method of the BUCK converter with a sliding mode control and discusses how to choose switch function on output voltage.Meanwhile,the dynamic quality of the sliding mode is analysed.This result can be applied to the design of controllers for Power Electronic Circuit.
