Vector control strategy of PMSM servo system based on auto-disturbances rejection controller

摘要

A vector control method for PMSM based on auto-disturbances rejection controller is designed. First, the mathematical model of PMSM is analyzed in dq coordinate system. Second, the vector control strategy of PMSM based on auto-disturbances rejection controller is designed, which consists of current loop, speed loop and position loop to form a three loop series structure. Finally, the simulation is performed on the computer. The simulation results show that the vector control strategy of PMSM based on auto-disturbances rejection controller can effectively solve the contradiction between rapidity and overshoot of linear control system and has good dynamic and static performance and anti-disturbance capability.
