摘　　要：基于变结构控制理论，阐述在滑模控制与ＤＣＤＣ功率变换器输入之间加入一带宽可调滤波器，该滤波器有效地削弱了抖振，并保留了滑模的优良特性，最后应用ＭＡＴＬＡＢ进行仿真。On the bases of the variable structure theory,a variable bandwidth filer is introduced between the sliding mode controller and DC DC converter input. The proposed method gives one of the effective method to reduce the chattering and to keep the good property of the sliding mode control.At last a MATLAB software is used for simulating and a good result is got.
