Abstract

Abstract: In order to further improve the running efficiency of induction motor, a new energy-saving control method was proposed. Considering the influence of varied flux, a control strategy coordinating the optimal flux with the optimal slip angular frequency based on the slip angular frequency control was built. The mathematical model of induction motor considering core loss was established. The expression of the optimal flux and slip angular frequency was obtained according to the Lagrange multiplier method when system was the highest efficiency. By using MATLAB simulation platform, a simulation model of the energy saving control system was built doing a research. The results show that this control strategy can not only improve the energy-saving effect, but also improve the dynamic performance of induction motor. So the control method is correct and feasible.
