一种buck型电源变换器的新型滑模控制器设计

A new sliding mode controller design of buck power converter

结合buck变换器电路的内部关系,从基于电感电流和电容电压的滑模面推导出一种只基于电容电压的新型滑模面,从而省去了对电感电流的测量.从仿真对比结果来看,这种控制可以得到比常规滑模控制更好的动态品质,对负载变化具有更强的鲁棒性.

This paper combining the inter construction of buck power converter induces a sliding surface based on the voltage from the sliding surface based on both the voltage and the current. The proposed control law do not need to measure the inductor current. A comparison study shows that this method works better, by which can acquire better dynamic quality and robust.
