摘要： 为进一步提高感应电动机的运行效率,提出了一种新型节能控制方法。该方法基于转差角频率控制,考虑磁链变化的影响,建立一种最佳磁链和最佳转差角频率协调控制策略。建立考虑铁损时感应电动机的数学模型,通过拉格朗日乘数法,求得当系统效率最高时所对应的最佳磁链和最佳转差角频率的表达式,利用MATLAB仿真平台,搭建节能控制系统的仿真模型并作仿真研究。结果表明,这种控制策略不仅能改善节能效果,而且可以提高感应电动机的动态特性,这种控制策略是正确和可行的。

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.

Key words: energy-saving control, induction motor, optimal flux, optimal slip angular frequency, MATLAB simulation
