Abstract

In sensorless control, sliding mode observer is widely used because of its insensitivity to parameter changes and strong robustness. For unnecessary high frequency chattering and the lack of accuracy in calculation of rotor position and machine speed in the conventional sliding mode observer, a new sliding mode observer based on the new constant velocity reaching law is used to suppress the high frequency chattering of the machine system. A new constant speed reaching law is designed to replace the conventional constant speed reaching law and it is introduced into new sliding mode observer. This method improves the approaching speed of sliding mode and reduces the high frequency chattering of conventional sliding mode observer. In addition, the arctangent function is used to estimate the position of the machine rotor, and the phase compensation for the Angle position error of the machine rotor is carried out. The simulation results show that compared with the Conventional sliding mode observer, the proposed new sliding mode observer is more stable and has better control performance.
