摘要
为了克服PMSM(永磁同步电机)DTC(直接转矩控制)系统的非线性和不确定因素的影响,引进了模糊PI速度调节器。在MATLAB下建立了基于此调节器的PMSM DTC系统,并与常规的PI速度调节器PMSMDTC系统进行了对比。仿真结果表明:模糊PI速度调节器可以大幅度地提高该系统的响应速度和稳定性。
In order to overcome the influence of non-linear and random factors,the paper introduces the PI controller based on fuzzy theory into the PMSM-DTC(permanent magnet synchronous motor direct torque control) system. It designs the system with the MATLAB/Simulink and compares it with the system based on normal PI controller under the same condition, the results show that it can improve response speed and stability obviously.
