Application of Fuzzy Control Theory in the Efficiency Optimisation of an AC Drive System

Dealing with the influence of air gap flux on the features of efficiency and dynamic /static behaviors of an induction motor, a novel method was presented . At adynamic state the rated flux was set,to be reduced at the static and light load to ob- tain the optimisation efficiency An online searching flux was analyzed using the fuzzy control theory. Simulation results of the system have been proved to be satisfactory .
