Abstract: Speed Sensorless induction motors have the attractions of low cost and high reliability.To replace the sensor,proposed the position sensethes indrution motor vector control system,based on TMS320LF2812 DSP.The paper presentsed the vector-controlled basic equation,due to the equation,built the model reference adaptive systerm for estimating the rotor flux link.Finally,compared the results between Matlab/Simulink simulation and the experimentation of the sensorless asynchronous motor vector control based on DSP.The results verify the simulation and system have the high identification precision, excellet dynamic,static perfomances and high control effect.
