PID Controller Based Multiple (Master/Slaves) Permanent Magnet Synchronous Motors Speed Control


This paper suggests the use of the traditional proportional-integral-derivative (PID) controller to control thespeed of multi Permanent Magnet Synchronous Motors (PMSMs). The PMSMs are commonly used in industrialapplications due to their high steady state torque, high power, high efficiency, low inertia and simple control of theirdrives compared to the other motors drives. In the present study a mathematical model of three phase four polesPMSM is given and simulated. The closed loop speed control for this type of motors with voltage source inverter andabc to dq blocks are designed. The multi (Master/Slaves approach) method is proposed for PMSMs. Mathwork'sMatlab/Simulink software package is selected to implement this model. The simulation results have illustrated thatthis control method can control the multi PMSMs successfully and give better performance.
