-This paper presents a novel maximum efficiency control scheme for convergence improvement in stator-flux-oriented induction motor drives. Three input powers are calculated at three different flux levels, respectively. A quadratic curve is obtained using the quadratic interpolation method using the three points. The flux level at the lowest point of the interpolated curve is calculated, which is not the real minimum input power of the motor, but an estimated one. Hence, the quadratic interpolations are repeated with three new points chosen using the selection method for new points for refitting until the convergence criteria are satisfied. The proposed method is verified by simulation results.

The paper presents an accurate loss model based controller of an induction motor to calculate the optimal air gap flux. The model includes copper losses, iron losses, harmonic losses, friction and windage losses, and stray losses. These losses are represented as a function of the air gap flux. By using the calculated optimal air gap flux compared with rated flux for speed sensorless indirect vector controlled induction motor, an improvement in motor efficiency is achieved. The motor speed performance is improved using a fuzzy logic speed controller instead of a PI controller. The fuzzy logic speed controller was simulated using the fuzzy control interface block of MATLAB/SIMULINK program. The control algorithm is experimentally tested within a PC under RTAI-Linux. The simulation and experimental results show the improvement in motor efficiency and speed performance.

“…Este procedimiento o estrategia de control, denominada como Minimum Losses Point Tracking (MLPT) por analogía con el Maximum Power Point Tracking del sector de la energía fotovoltaica [103], se inspira en el método perturb and observe [104] para determinar el punto de funcionamiento de mínimas perdidas en base a una medida de la potencia consumida por el accionamiento en su conjunto. Esta idea fue aplicada por primera vez en máquinas de inducción para resolver el mismo problema: optimizar la eficiencia energética mediante la determinación empírica del flujo óptimo [105,106]. Posteriormente la propuesta fue trasladada a máquinas síncronas de imanes permanentes [107,108] e incluso a máquinas síncronas de reluctancia [109], pero desde que se desarrolló el control MTPA parece que ha perdido interés y ha pasado a un segundo plano.…”
