| 摘 要： | 由于全桥软开关变换器为强非线性时变系统,工作特性复杂,传统的PID控制器不具有在线自整定功能,控制效果较差,不能满足过程控制日益发展的需求。为了得到良好的控制效果,提出了采用PID参数模糊自整定控制变换器。在变换器数学模型的基础之上设计控制器,通过MATLAB/Simulink对其仿真。仿真结果表明:PID参数模糊自整定控制系统比传统的PID控制器超调量小,调节时间短,控制效果有明显的改观。

| Abstract: | Because of strongly nonlinear time-varying system of the full-bridge soft switching converter with complex working characteristics, traditional PID controllers do not have online self-tuning function and their poor control effect cannot meet the requirement for the development of process control. In order to achieve good control effect, this paper presents a fussy self-tuning control converter adopting PID parameters. In this paper, the controller is designed on the basis of the mathematical model of the converter, and is simulated through MATLAB/Simulink. The simulation results indicate that the fuzzy self-tuning control system adopting PID parameters has a smaller overshoot volume, shorter adjustment time and much better control effect than traditional PID controllers. |
