Abstract
In order to improve the asynchronous motor speed sensorless vector control system of low speed performance and reduce the sensitivity of the change of motor parameters, and proposes an improved rotor flux estimation method, based on model reference adaptive (MRAS) observation speed. The simulation results show that the method of the parameters of the motor change good robustness, flux estimation precision, fast convergence rate, low speed stable performance. Based on the improvement of the flux observer as reference model can realize asynchronous motor speed sensorless vector control system of high performance operation.关键词
