Abstract
In view of problem of low efficiency existed in traditional indirect vector control system of induction motor based on rotor flux linkage orientation under light load, the paper proposed a design scheme of introducing fuzzy energy-saving control method based on on-line searching into traditional control system of induction motor. The scheme uses indirect vector control method based on rotor flux linkage orientation in transient operation of motor, and uses fuzzy energy-saving control method based on on-line searching in stable operation of motor, which taking DC input power as control variable to make fuzzy optimization control, so as to make motor operate at maximum efficiency. The simulation result proved correctness and effectiveness of the scheme.
