Simulation research on switched reluctance motor using direct instantaneous torque control based on RBF network

该文用RBF神经网络构成的自适应PID控制器,代替常规PID控制器,提出一种采用直接瞬时转矩控制方法(DITC)来抑制开关磁阻电机的转矩脉动的新方法。采用Matlab/Simulink进行了开关磁阻电机DITC系统转矩脉动抑制的仿真研究。仿真结果表明,该种方法不仅能够很好地抑制转矩脉动,而且系统具有超调小、响应快、控制精度高等优点,验证了该方法的可行性。

In this paper,a new method is introduced that use RBF neural network of adaptive PID controller instead of the conventional PID controller,and the control principle adopt direct instantaneous torque control（ DITC） to inhibition of switched reluctance motor torque ripple. Simulation of switched reluctance motor＇s system for DITC uses Matlab / Simulink. Simulation results show this kind of method has many advantage,it can not only good torque ripple suppression,but has a small overshoot,short response time,high precision control. And verify the correctness of the methods.
