Abstract：For the interior permanent magnet synchronous motor (IPMSM) is difficult to estimate rotor position from flux, a novel sliding mode observer (SMO) via the current error is presented to estimate rotor position and speed based on the linear flux. In this way, the phase lag caused by the extra low pass filter is eliminated and the robustness of estimated position and speed is improved. The full digital IPMSM sensorless vector control simulating system is built under the field-circuit coupled circumstance. Simulations can reflect the sensorless performance and the coupling characteristics between IPMSM and control system. Experimental and simulation results show that the validity of the algorithm.
