摘要：
This paper presents an improved Non-singular Terminal Sliding Mode observer for the estimation of the speed and rotor position of permanent -magnet synchronous motor (PMSM). The proposed observer based on an improved non-singular Terminal sliding mode (NTSM) can obtain the information of the running state of the motor accurately and quickly without mechanical sensors. The reliability and robustness of the PMSM's space vector control system will be raised for the realization of the sensorless control. The simulation results show that the method is valid.
