【Abstract】 In this paper, the method for speed and rotor position estimation of permanent magnet synchronous motors based on dSPACE has been studied. By using the technology of extended Kalman filter and monitoring stator voltages and currents, it is possible to estimate speed and rotor position in real time and implement PMSM drives without position and speed sensors. The experiment results show the efficiency of the method.更多还原
