| 摘 要： | 提出一种变结构控制方法,用两个滑模面分别实现DC-DC变换器内外环控制,内环滑模面用于电流控制环,外环滑模面用于电压控制环.以BUCK变换器为例,通过仿真和比较表明,这种控制可获得比单滑模面控制更多的反馈信息,得到更好的动态品质,对参数的摄动和外界干扰具有很强的鲁棒性,抖振很小,且稳态误差也很小.

| Abstract: | This paper presents a double sliding surface VSC(variable structure control) method.It constructs two loops controller,in which one sliding surface adopts the inductor current as the feedback parameter of the inner loop and the other sliding surface adopts the capacitance voltage as the outer.Taking BUCK converter for example,through the simulation and comparison,we can find this control strategies are better than the single surface VSC.It can obtain much more feedback informations and better dynamic responses,and can be maintained in spite of large input voltage,output current,and strong robustness.And it can eliminate chattering effectively and good reduce steady-state errors. |
