This paper presents a new online loss-minimization algorithm in the adaptive control model for speed sensorless based on the Direct Rotor Flux Oriented Control (DRFOC) with optimum flux in the condition of do variable stator resistance. The paper also presents a new approach to develop a reference and adaptive models to estimate the speed and to observe stator resistance change. Simulation results in Matlab Simulink showed good adaptability of the presented model controls even when the stator resistance changes to up 200% of rated. In addition, using the proposed algorithm allows reducing losses and improving efficiency of proposed control model in comparison with DRFOC traditional model for load range 0-70% of the rated. Where the difference of efficient can reach 42%, and the difference in loss to 85%.
