摘要：
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.
