永磁无刷直流电机的比例谐振控制
Proportional Resonance Control of Permanent Magnet Brushless DC Motor
摘要
Abstract
For permanent magnet brushless DC motor(BLDCM)in the running process of the system stator current oscillation and output torque jitter and other issues,a method based on proportional resonant(PR)brushless DC motor speed control program was proposed. The PR controller was used instead of the PI controller in the current closed loop control,the adverse effects of using PR controller to infinite open-loop gain at the resonant frequency of the interference suppression system bring cycle,in order to effectively weaken the interference of harmonic stator current and stator current oscillation suppression,thus improved the overall performance of the control system. Matlab simulation results show that the speed control scheme of BLDCM based on proportional resonant control effectively suppresses the oscillation of motor stator currents and the jitter of steady-state output torque with load.关键词
