Abstract :
In this paper, performance analysis of an induction motor drive employing a loss minimization algorithm (LMA) is presented. As the induction motors are not designed to impart high efficiency under partial loading conditions, proposed LMA is used to improve the efficiency under such load conditions. For the efficiency improvement LMA uses the rotor flux as a control variable. Mathematical model of induction motor in field-oriented frame, including proposed loss model is derived. The complete drive system is simulated in MATLAB/Simulink software for different operating conditions. Simulation results obtained shows the effectiveness of the proposed algorithm in partial loading conditions.
