【Abstract】 On the basis of analyzing the basic principle of vector control in permanent synchronous motor(PMSM) drive,a novel intelligent vector controller is proposed.Here,neuron is used in speed control,ANN is used in pulse width modulation(SVM).Neuron based speed controller has a simple structure and a small amount of computation,which results in not only fast dynamic response but also high steady-state accuracy.Meanwhile,an artificial neural network based SVM(ANN-SVM) algorithm can be realized easily with efficiently-reduced current harmonic.A PMSM drive simulation model with intelligent vector control is created and studied using Matlab/Simulink.The simulation results demonstrate the feasibility and validity of the intelligent vector controller.更多还原
