Abstract:
A hybrid search method is proposed for the efficiency optimization of vector controlled induction motors.This method gives fuzzy logic based adaptive search steps and then switches to the golden section technique to obtain a fixed convergence rate.Such a procedure reduces torque pulsation and avoids search oscillation around the optimal flux.Simulation results with a lossy model of a vector controlled induction motor show the feasibility of the method.
