摘要

This paper deals with on-line real coded genetic algorithms optimization based on vector control for loss minimization operation of induction motor. Losses minimization is obtained by adjusting the magnetizing current component with respect to the torque current component to give minimum total copper and iron losses. Some simulation results are obtained by using both online real code genetic algorithm optimization and minimal function which use the derivative of the total losses of the motor. Those results are compared with the field-oriented control method without optimization. Results show that the efficiency of induction motor can be improved under different operational conditions especially in light load region.
