| Abstract: | This paper introduces a vector control system based on direct rotor field oriented control for sensorless induction motor drive. Stator and rotor adaptive flux observer and speed dynamic estimator are used to estimate the flux and speed of the rotor and three PI controllers are supposed to control the speed and current of torque and flux, then produce the voltage space vector to control the motor. The simulation results demonstrate the good performance for the system in observation precision, robustness and dynamic and steady aspects. |
