摘要
由Buck电路的状态空间平均法,可得到其电压控制下的动态小信号模型,并应用PID实现其精确控制。为提高控制精度和抗干扰能力,用模糊控制器对PID参数进行实时整定。
It is presented how to use the fuzzy-PID methodology to control Buck converter with the average state space method. The fuzzy regulators are used to tune the gams of the PID controllers. With this method, the output voltage can be controlled accurately. The simulations and experiments show the great accuracy improvement.
