Abstract: Speed sensorless induction motor have the advantages of low cost and high reliability.To replace the sensor,position sensorless asynchronous motor vector control system based on TMS320LF2812 DSP had proposed.The paper presented the basic equation of the vector control,due to the equation,builts the model referrence adaptive systerm for estimating the rotor flux link.Finally,comparing the results between Matlab/Simulink simulation and the experimentation of the sensorless asynchronous motor vector control based on DSP,and the results verify the simulation and the practical motor contro system experimentation both have satisfactory identification precision,excellent dynamic and static perfomances,and also have high control effect.
