| Abstract:In order to improve the running efficiency of induction motors, a fast response and energy saving control method is proposed. Based on the vector control theory, an energy saving control strategy of the optimal flux of induction motors with torque control and flux regulators is built. At first, a mathematical model of induction motors considering core loss is established. Then, the expression of the optimal flux that is obtained when the system is at the highest efficiency is obtained according to the numerical analysis method. Finally, the simulation model of the energy saving control system is built by MATLAB. The simulation results show that the control strategy can not only improve the energy saving effect, but also improve the dynamic performance of induction motors. Thus, the control method is correct and feasible. |
