三相电压型PWM 整流器是一个强非线性系统,采用常规线性控制难以达到理想的控制效果,动态性能差且参数调节复杂.滑模控制(SMC)可有效解决非线性系统的控制问题.针对电压外环采用滑模控制而电流内环采用非滑模控制方案对PWM整流器整体动态性能和鲁棒性的影响,提出了电压外环和电流内环均采用滑模控制的双滑模控制方案.给出了双滑模控制系统的详细设计过程,并通过Matlab/ Simulink 搭建了系统仿真模型,对双滑模控制方案和电压外环采用滑模控制尧电流内环采用PI 控制方案进行对比仿真.结果表明,采用双滑模控制的PWM整流器系统不仅设计和实现简单,而且具有更优越的鲁棒性和动态性能.

Three-phase voltage source PWM rectifier is a strongly nonlinear system. It is difficult to achieve the ideal control effect using the conventional linear control method for its poor dynamic performance and complicated parameters adjustment. Sliding Mode Control （SMC） is able to effectively solve the above problem. The method of output voltage loop using SMC and inner current loop using non-SMC would have negative effects on the whole dynamic and robustness, so the double SMC and the strategy of output voltage loop using SMC and inner current...
