摘要
针对直接转矩控制中电机低速运行时定子电阻变化对系统性能影响较大的问题,提出了一种基于小波网络的定子电阻辨识方法,并对该方法进行仿真研究。仿真结果证实,该文所提的辨识方法优于 BP 神经网络。通过该方法可以有效的提高交流电机的低速运行性能。
To solve the effect of stator resistance change of the low-speed performance in direct torque control (DTC), one kind of observers, based on the wavelet networks (WN) is introduced. Simulation method is used to prove the efficiency of this method. The simulation result proved that the method we supply is supper than the BP neural network (NN). It is an effect way to improve the low-speed performance.
