| 摘 要： | 与经典的PID控制器不同，模糊控制不需要获取系统精确的数学模型．根据系统的要求，设计模糊控制器，以给定参考电压与实际电压之间的偏差及其微分作为输入，通过合理的推理规则，得到占空比输出，去控制开关管的开关时间．论述了模糊控制器的详细设计过程，以及在MATLAB中建立仿真模型的过程．仿真结果表明系统具有较好的稳态和动态性能．

| Abstract: | The research of a DC-DC switched mode power supply based on fuzzy control,which is different from classic PID control,and does not require accurate mathematical model of system,is introduced.The fuzzy controller is designed according to the system’s requirements.The error between the reference voltage and the practical output voltage,and the differential of error are set as the input of the controller.According to proper rules,the output of the controller-duty cycle is obtained to controller the switch.The design process and the simulation model in MATLAB of the fuzzy controller are introduced in detail.The simulation results show that the system works with good stability and dynamic properties. |
