In this paper,we propose a control scheme for thespeedservocontrolofPMLSMwithmodelrefe rence adaptive and neural network techniques.In order to improve the robustness of the system,we use on line indentification technique to compensate the variation of the parameters and modify the calculation of the neural networks's teacher value.The simulation shows that the system has good speed servo performance,especially in overcoming the effect of the effect which PMLSM has.
