摘　　要：根据三相电压型整流器在dq坐标系下的数学模型,应用非线性微分几何理论中的状态反馈线性化方法,采用直接电流控制策略,设计了基于PI控制器的闭环控制系统。该控制系统能将有功功率和无功功率解耦,并可以对PI控制器参数进行有效的整定。仿真结果表明所提出的控制策略是可行的。According to the mathematical model of three-phase voltage source rectifier in the dq axis coordinate system, the PI controller based closed-loop control system is designed with the method of state feedback linearization in nonlinear differential geometry theory and the direct current control strategy. The control system is able to decouple the active power and reactive powers, and to set effectively the PI controller＇s parameters. The simulation results show that the proposed control strategy is feasible.
