@@@@A kind of vector control system without speed sensor for asynchronous motor, in which the model reference adaptive system(MRAS) was used to estimate the rotor speed, was introduced. This system was simulated by means of MATLAB/Simulink, the simulation result showed that this system had better static and dynamic performance and stronger robustness, capable of possessing the similar control effect by vector control with a speed sensor.
