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PMSMDTC系统,并与常规的PI速度调节器PMSMDTC系统进行对比,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 writer introduces the PI controller bassed on fuzzy theory into the PMSM-DTC(permanent magnet synch motor-direct torque control) system.Designing the system with the Matlab/Simulink and comparing it with the sysytem bassed normal PI controller under the same conditions,the resultes show that it can improve obviously rapidity of reponse and stability.
