| 中文摘要: |
| 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。 |

| 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. |
