摘要:
 针对移相全桥DC-DC变换器,为了进一步提高其动态性能,找到一种理想的控制策略,文中通过对降压型移相全桥DC-DC变换器进行小信号分析,得到降压型移相全桥DC-DC变换器的数学模型.根据降压型移相全桥DC-DC变换器的数学模型,采用三种控制策略,分别设计了PID控制器、模糊控制器和模糊PID控制器.仿真实验结果表明,模糊PID控制器结合了PID控制器和模糊控制器的优点,其超调量小、调整时间短和稳态误差小.因此它具有更好的控制效果,是一种更实用的控制策略.
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.
