Abstract

The paper introduces the mathematical model of permanent magnet synchronous motor(PMSM) in the dq coordinate system and αβ coordinate system, and investigates two direct current control strategy of AC current tracking and dq current control technology. The paper analyzes detailed the operating principle of two control strategies, and makes simulation experiments in Matlab/Simulink. The simulation results show that PMSM has good dynamic and static performance under two direct current control method. Compared with AC current tracking method, PMSM in dq current control method has better steady-state characteristics, and current ripple and torque ripple is smaller when the motor speed is changed suddenly.
