摘要
分析比较了现有的几种PWM型DC DC变换器非线性控制方法 ,介绍控制策略的基本构成 ,指出了各自的优点和不足 ,并以Buck型DC DC变换器为例 ,给出了相应的仿真波形和对比分析。
Switching converters are pulsed nonlinear dynamic systems,as requirement of modern industry for advanced control system,the conventional linear feedback control can not satisfied for the requirement.There has been an attention in the power electronics community for nonlinear control.This paper introduces several nonlinear control methods for PWM DC DC converter,illustrates their basis principles,points out their advantages,disadvantages and the simulation waveform. Comparative analysis are provided with Buck converter.
