In this paper, a sensorless Direct Torque control (DTC) for Permanent Magnet Synchronous Motor (PMSM) drive based on Adaptive Model Reference (MRAS) algorithm and PI with adapted gains fuzzy logic (FL) are presented. The MRAS is utilized to estimate speed and stator resistance and compensate the effects of parameter variation on (stator resistance variation introduce errors flux and torque estimation and affect the performance of DTC). In other hand, speed regulation by PI with two adaptive FLC is investigated and compared with classical PI controller. Simulation results are presented and show the effectiveness of the proposed method.
