Sensorless Control of Permanent Magnet Synchronous Motor Based on the Improved Sliding Mode Observer

Sliding mode observer (SMO) which has a strong robustness is used in the sensorless control system of permanent magnet synchronous motor (PMSM). The method is usually used to estimate the rotor position although it has the chattering problem. According to the causes of the chattering in traditional...
