This paper presents the modeling of Permanent Magnet Synchronous Motor (PMSM) drive which is modeled by using vector control and design of controllers for the reliable operation of Permanent Magnet Synchronous Motor. The motor model of both surface mounted (SPMSM) and interior PMSM (IPMSM) along with the controller is first simulated in MATLAB Simulink. Two different design methods are used for speed and current controllers design. The current controller is designed using the magnitude optimum method where the controller time constant is set such as to eliminate the largest time constant of the motor model. The outer speed controller is designed using symmetric optimum method. Both the methods are explained in detail in this paper. For the field weakening the negative d-axis current is injected to the motor and the speed above the rated speed is obtained. |
