基于 Buck 变换器的滑模控制方法研究
Research of Sliding Mode Control Method Based on Buck Converter
摘要
Abstract
For faster to obtain ideal DC output voltage and optimize Buck converter dynamic perform-ance, this paper uses the sliding mode control method .A modified double exponential reaching law is proposed , which replaces symbol function into saturated function and adds an exponential term on the double exponential reaching law .The validity of the algorithm is verified and a method for calculating the arrival time of the control system is given .The simulation results show that this kind of sliding mode con-trol strategy overcomes the shortcomings of long reaching time and big chattering , and it also ensures dy-namic quality of the system .关键词
