This document deals with a sensorless field oriented control (FOC) for permanent magnet synchronous motor (PMSM) drives by using a full order sliding mode observer (FOSMO). We have constructed a FO-SMO to estimate the position and velocity. The Lyapunov theorem is used to verify the FO-SMO stability. The experimental findings indicate the robustness of SM observer under parametric variations.
