摘　　要：分析了基于功率控制的Buck变换器的小信号模型,探讨了斩波器中反馈控制的传递函数和环路参数的设计,设计了双极点、双零点的PI补偿器。实验结果表明,补偿后的系统不仅提高了系统响应速度,而且消除了稳态误差,系统性能明显提高。Analyzes the small-signal model of Buck converter based on power control,discusses the designs of transfer functions and loop parameters of feedback control in the chopper,and designs the bipolar and double-zero compensator. Experimental results show that the compensated system not only improves the response speed of the system,but also eliminates the steady-state error,and the system performance is improved significantly.
