移相全桥DC-DC变换器控制策略的仿真研究
Simulation Research on Control Strategy for Phase-shift Full-bridge DC-DC Converter
摘要
Abstract
For the Phase-Shifted Full-Bridge ( PSFB) DC-DC converter,in order to further improve its dynamic performance and find an ideal control strategy,the mathematical model of the BUCK PSFB DC-DC converter can be obtained by the small-signal analysis method. According to the mathematical model,three control strategies are adopted to design PID controller,fuzzy controller and fuzzy PID controller. The simulation shows that the fuzzy PID controller combines the advantages of PID controller and fuzzy controller,which has the advantages of small overshoot,short adjustment time and small steady state error. So it has better control effect and is a more practical control strategy.关键词
