Abstract

A linearized mathematical model of Permanent Magnet Synchronous Motor is proposed with the help of vector control method and the definition of new variables. Then Linear Quadratic regulator (LQR) control methodology is investigated and an optimal speed controller is designed for PMSM system. The control performance of LQR is compared with that of traditional PID controller in Simulink environment of MATLAB. Simulation results indicate that the PMSM system using proposed LQR control methodology has better dynamic performance and stronger robustness than using traditional PID controller.

INTRODUCTION
In this paper, vector control theory [1] is discussed in control of PMSM. It is because of the vector control theory that performance of PMSM servo drive reaches and even surpluses that of dc drives. Vector control theory with the help of the principle of Clarke and Park transforms, transforms the actual three phase current into the corresponding torque current and field current in order to decouple the mathematical control model of PMSM. As the PMSM motor is replacing the conventional dc motor for small output power rating variable speed control system, the performance of PMSM which requires quick transient response must be improved [2]. PID controller has been dominating the control system of PMSM especially in practical conditions, however the performance of PMSM using PID controller is not always satisfactory. Hence, alternative methods like Linear Quadratic Regulator (LQR) is being used in speed control of PMSM [3][4]. LQR is an optimal control methodology that uses the quadratic cost function to determine its control performance. In order to apply LQR to the speed control system of PMSM, however, the original non-linear, mathematical model of PMSM must first be linearized. The linearization method proposed in [5][6] was used.
