Speed Control of Permanent Magnet Synchronous Motor Using Universal Bridge and PID Controller

摘要

The permanent magnet synchronous motor (PMSM) are commonly used in industrial application due to their high steady state torque, high power, high efficiency, low inertia, and simple control to their drives compared to the other motor drives. This paper suggest the use of the proportional integral derivatives (PID) controller to control the speed of PMSM. The closed loop speed control for this type of motors with voltage sources inverter and universal bridge are designed. The whole drive system is simulated in Matlab/Simulink based on the mathematical model of the system device including PMSM and inverter. The aim of the drive system is to have speed control over wide speed range. Simulation results show that the speed controller has a good dynamic response and can control the PMSM successfully with a better performance.
