摘　　要：研究了梯形波无刷直流电动机控制系统稳定性问题。在负载转矩、转动惯量、阻尼系数和绕组电流等发生波动引起转速变化时,根据模型参考自适应控制原理构造参考模型,设计转速自适应控制律,使控制系统具有较强的鲁棒性和稳定性。通过仿真和实验证明,该模型参考自适应控制器能够准确跟踪给定的参考速度。The control system＇s stability problem of brushless DC motor（BLDCM）is presented in this paper. When the velocity changes by the variations of the load torque,the moment of inertia,damping coeficient,phase currents and so on ,the reference model is established and the adaptive control algorithm of the velocity is derived based on the model reference adaptive control （MRAC）. Then the control system will be strongly robust and stable. Simulation results indicate that the proposed model reference adaptive controller of the BLDCM can track the desired velocity accurately.
