A multilevel Neural netw ork is designed in this paper. The Neural netw ork can distinguish the dynamic performances of the system and control brushless DC motor to make speed follow the orbit that is choosen in advance, and the follow ing precision is high. The system is modelled and simulated in M atlab/ Simulink. The result shows that the system using the ap proach can greatly improve the performance of speedadjustment system.
