中文摘要：

针对PWM整流器控制策略存在的滑模控制的稳态性能较弱、无源性控制的动态追踪性能较差等问题,本文以整流器拓扑结构为研究对象,提出了一种协调控制的方法,给出了PWM的EL数学模型,分别求出系统的无源性控制器和滑模控制器。在此基础上,设计出协调控制函数,并分析了系统稳定性。为验证本文方法的准确性,采用Matlab/Simulink进行仿真分析。仿真结果表明,协调控制能达到动态迅速跟踪、直流输出恒定和单位功率因数等运行目标,能够满足对整流器的控制要求,有效减小扰动对系统影响。与无源性控制相比,该方法充分结合了二者的优点,即快速的跟踪性能和优良的稳态特性。该研究应用前景广阔。

英文摘要：

Aiming atsome questions existing in the PWM rectifier control strategy, for example, the steady- state performance of sliding mode control is weak, and the dynamic tracking performance of the passive contro- lis poor, in this paper, a method of coordinated control is proposed based on the topology of the rectifier, and the EL mathematical model of PWM is given, and the passivity controller and sliding mode controller are ob-tained respectively. Based on this, the coordination control function is designed, and the stability of the system is analyzed. In order to verify the accuracy of this method, Matlab/Simulink is used. The simulation results show that the coordinated control can meet the requirements of achieving fast dynamic tracking, DC output con-stant and unity power factor, meet the control requirements of the rectifier and reduce the influence of disturb-ance on system effectively. Compared with passive control, the proposed method can combine the advantages of the above two methods, namely, achieving fast tracking performance and good steady-state performance. The research prospect is broad.
