| Abstract: | In order to realize the real-time identification of motor rotor speed,this paper proposes to estimate the motor speed by the voltage and current measured at the end-region of motor.Through the estimation,the model reference adaptive control for the vector control of speed sensorless can be achieved.In the MATLAB/Simulink,the vector control system of speed sensorless based on this method is established and the simulation experiment is carried out.Simulation result shows that this system enjoys good static & dynamic state character and stability. |
