The simulation research of permanent magnet synchronous motor vector control system
Electrical Engineering and Automation Specialty
Abstract:As a new style motor, permanent magnet synchronous motors are receiving increased attention for drive applications because of their high torque to ratio, Permanent magnet synchronous motors(PMSM) are becoming attractive in many application of industry and daily life.
Based on summarizing the PMSM and its control technological development situation ,this paper infered the PMSM mathematical model and the equivalent circuit, and detailed its principle of vector control, and analyzed the id=0 control, biggest torque/current control, flux-weaked control and so on. At the end of the paper, the simulation research of id=0 PMSM vector control system is carried out with Matlab /simulink tool ,the simulation results prove the control method accuracy, and provides the theory basis for the actual motor control system design.
