摘　　要：文章在分析基于功率控制的Buck变换器的小信号模型的基础上,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。A two-pole and two-zero PI compensator is designed in this paper. It is based on the analysis of the smallsignal model of Buck converter in power control ,and the discussion of the design of transfer function and loop parameters in converter. The experimental results show that the compensated system not only improves the system response speed,and eliminates the steady-state error, system performance improved markedly.
