Abstract: Being the most widely used motor in all types of industrial and domestic applications, operation of the induction motor at optimal efficiency is paramount for conservation of energy. This paper presents simple and easily realizable techniques for implementation of a PI and Fuzzy Logic controller based efficiency optimization algorithm for a vector controlled induction motor drive. This is obtained by optimal control of the flux current component of the IM drive to reduce the core losses under light load conditions. A new approach to optimize the efficiency based on optimal control of iron losses only is introduced and compared with the optimal control of the total losses. The developed algorithm is simulated using MATLAB/Simulink and is tested under different operating conditions.
Keywords: Dynamic model, efficiency, induction motor, iron losses, optimization, vector control
