利用直接瞬时转矩控制( DITC)方法改善开关磁阻电机( SRM)转矩脉动过大的问题。将模糊逻辑与PI控制相结合形成模糊自适应PI控制策略,构成了SRM的调速系统,改善了SRM高度非线性难以用传统PI控制取得较好控制效果的问题。仿真结果表明,DITC方法能够有效地控制转矩,转矩波形明显优于传统控制方法的转矩波形,有效地抑制了转矩脉动。模糊自适应PI控制器对高非线性的SRM取得较好的控制效果,提高了系统动态响应,减小了超调量,稳定性强。

The method of direct instantaneous torque control ( DITC) was used to improve torque ripple of the switched reluctance motor ( SRM) . And fuzzy logic was combined with the PI control to form the fuzzy adaptive PI control strategy, which made up the SRM speed control system, and improved the problem that SRM is highly nonlinear and difficult to use traditional PI control to achieve better control effect. The DITC simulation results indicate that the method can effectively control the torque, and torque waveform is superior to that of the traditional control method, which effectively suppresses the torque ripple. Fuzzy adaptive PI controller for nonlinear SRM achieves good control effect, and realizes the system dynamic response, less overshoot volume, strong stability.
