摘要
This paper presents a sliding mode observer to estimate the position and speed of a Permanent Magnet Synchronous Motor (PMSM). The observer error under parameters' detuning is analysed. Simulation results showed that the observer is robust to the parameter uncertainties. An adaptive gain scheduling is used to increase the observer speed of convergence. A phase-compensation is introduced to minimize the unwanted phase lag introduced by the observer low pass filter. The observer lowest speed is 0.5 rad/s.
