Abstract

Permanent magnet synchronous motor (PMSM) is required to the speed and position information for motor speed and torque controls. However, to apply the sensors has many problems that are sensor mounting space and additional cost, etc. Therefore, in this paper, sensorless control method based on model reference adaptive system (MRAS) is proposed to eliminate the sensors. The method is constructed in 2 models that are a reference block as standard model and an adaptive block as the state observer model. The proposed control scheme is verified by the simulation.
