Research on deadbeat Current Control Strategy of Three-Phase PWM Voltage Source Rectifier
Dynamic response slow and DC voltage fluctuation when traditional current inner loop controller based on dq transformation applications in three-phase PWM voltage source rectifier (VSR).To these shortcomings,firstly this paper established discrete mathematical model of VSR,derived deadbeat control strategies based on deadbeat control theory for VSR.Secondly,design a double-closed-loop controller with current inner loop and voltage outer loop for the system.Finally,set up a Matlab/Simulink simulation platform of three-phase PWM voltage source rectifier to verify the theoretical analysis results.The results show that the three-phase PWM voltage source rectifier based on the deadbeat control in stabilizing DC voltage,control the AC current,etc,it has good steady-state and dynamic performance.The control method is simple,easy to implement,and has a certain practical value.
