【Abstract】 On the basis of analyzing the mathematic model of the permanent magnetism synchronous motor(PMSM),a novel based on grey theory rotor position and speed estimation scheme is suggested,which will meet the need of sensorless operation for PMSM.A sensorless vector control system of PMSM is set up based on this position and speed estimation approach.The proposed strategy has been achieved in digital signal processor(DSP) TMS320LF2407A.The experimental results show that the proposed control methods can solve the problem of rotor speed and position estimation and improve the control system robustness.The dynamic and static performances of the proposed control methods are good.更多还原
