摘要
针对永磁同步电机(Permanent Magnet Synchronous Motor,PMSM)控制系统转矩脉动大的问题,提出一种基于恒定开关频率的永磁同步电机直接转矩控制。利用三角波载波,将其应用到直接转矩控制系统(Direct Torque Control,DTC)中,达到减小转矩脉动,提高系统鲁棒性的效果。利用Matlab/Simulink仿真软件证实所提方法的有效性。
To solve the problem of large torque ripple in permanent magnet synchronous motor（PMSM）control system,adopt a new kind of based on constant switching frequency of permanent magnet synchronous motor direct torque control method,The triangular wave carrier is applied to the direct torque control system（DTC） to reduce the torque ripple and improve the system robustness.The effectiveness of the proposed method is verified by Matlab/Simulink simulation software.
