Abstract :
In order to avoid the influence of speed sensor and the parameter change as a result of the temperature variety on the system performance, a sensor-less vector control system based on model reference adaptive system (MRAS) for asynchronous motor is described in this paper. The rotor speed and magnetic flux are identified online with full order adaptive observers correctly and rapidly. The simulation result indicates that the system can meet the demand of the performance, and resist the disturbance of the load.
