一种基于内模控制的三相电压型PWM整流器控制方法
A Control Strategy of Three-Phase PWM Rectifier Based on Internal Model Control
摘要
Abstract
The three-phase PWM rectifier has been widely used because it can reduce the harmonic pollution of the power grid and has a high power factor.Traditionally,it adopts two-closed-loop control method and its inner-current loop uses the PI controllers with voltage feed forward decoupling.However,needing the precise mathematical model and hard to adjust due to various PI parameters are the disadvantages of the PI control method.In order to overcome the above problems,this paper brings IMC in the inner-current loop control of PWM rectifier and the conventional PI method is replaced by internal model controller.The simulation and experimental results show that the rectifier system has a high power factor and a well sine input current,meanwhile,it can resist the changes of load and dc line voltage.Also,the inner-current loop has a good follow performance and dynamic performance.关键词
