DC-DC变换器新型趋近律滑模控制
Sliding Mode Control of DC-DC Converter Based on Novel Reaching Law
摘要
Abstract
To solve the problems of long reaching time and serious chattering in DC-DC converter when a traditional constant-speed reaching law is used,a control method with a novel reaching law is proposed to improve the speed of reaching the sliding mode surface and inhibit the inherent chattering problem in the sliding mode variable structure con-trol system. Meanwhile,inductance current state variables are added based on a mathematical model of voltage step-down variator under the traditional sliding mode voltage control(SMVC). Finally,a Buck converter sliding mode con-troller is designed using the new reaching law,and it is compared with PI controller and constant-speed reaching law method. Simulation results show that the proposed control method can effectively improve the static and dynamic charac-teristics of the system,as well as its robustness .关键词
