| 摘 要： | 利用Matlab/Si mulink工具箱对500 W移相全桥(phase shift full bridge,PSFB)DC/DC变换器建立仿真模型,分别采用传统的PID、模糊PID、神经网络PID等控制方式对系统进行仿真.仿真结果表明:模糊PID和神经网络PID控制方式在调节时间、负载突变等情况下的性能均明显优于传统的PID控制方式.

| Abstract: | A simulation model of a 500 watts PSFB(phase shift full bridge) DC/DC converter is established by using the Simulink toolbox in Matlab.The traditional PID control strategy,fuzzy PID control strategy,neural network PID control strategy have been used to simulate the model individually.The simulation results prove that fuzzy PID control strategy and neural network PID control strategy are superior to the traditional PID control strategy in regulation time and the features when the abrupt load change occurs. |
