摘　　要：采用模型参考自适应法设计了无速度传感器矢量观测器。现以电压模型为参考模型,电流模型为可调模型,推算出速度信息,计算输出控制信号,实现了对感应电机的精确控制;通过Matlab/Simulink对其进行仿真、验证,结果表明,该系统对定子磁链观测精度高,速度估计准确,改善了电机的控制特性。A kind of sensorless vector control of induction motor based on model reference adaptive system is designed. The speed signal is estimated by using the voltage model as reference model, and using the current model as the adjustable model. The approach is implemented on Matlab/Simulink software. The simulation results show that the method gives satisfying estimation of stator flux and rotor speed in the whole speed range.
