Aiming at the problems of large chattering and slow response time existing in the preexisting sliding mode observer permanent magnet synchronous motor control, this paper proposes a new sliding mode observer control way. The model of the permanent magnet synchronous motor was established, and design a new function to take the place of the preexisting transforming function. And use Lyapunov stability criterion to analyse the system stability. At the same time, Use Matlab/Simulink simulation software to carry out simulation experiments, build simulation experiment models, and obtain the control result waveforms of the integrated sliding mode observer control system and the newly designed sliding mode observer control system. Compared to pre-existing sliding mode observers, it can be known that, constrasted with the pre-existing sliding film observer, better performance and stronger stability are possessed by the new sliding mode observer proposed in this artical.
