摘　　要：以异步电动机矢量控制的基本方程式为基础,构建了一个无速度矢量控制系统,并且采用了改进积分型转子磁链估算模型。根据模型参考自适应的速度推算,提出了一种改进的速度推算法。利用Matlab/Simulink对系统进行了仿真,仿真结果表明推算转速和实测转速几乎没有差异。The speed sensorless vector control system was established based on the fundamental equations of induction motor for vector control. flux estimation model is used. An improved speed estimation the speed of model reference adaptive system. The system is simulated by MATLAB/SIM-ULINK. Simulation results proves that the estimation speed is as same as the measured one.
