摘要：针对异步电机轻载工况下运行效率较低的问题，提出一种基于粒子群优化算法的节能控制方法。在电机损耗模型控制策略的基础上，建立考虑铁损的异步电机损耗模型，将粒子群优化算法用于电机任一工况下最优磁链的搜索，并将此最优磁链作为按转子磁场定向矢量控制的给定值，使电机始终运行在低能耗状态。仿真及实验结果证明了粒子群算法效率优化控制的有效性。

Abstract: This paper proposed an energysaving control method based on particle swarm algorithm, which aimed at the low operating efficiency of asynchronous motor under light load. On the basis of loss Model control, built the loss model of asynchronous motor which contained iron loss, and applied the PSO algorithm in the search of optimum flux and regard it as the given value of vector control which was based on the rotor magnetic field orientation, which made the motor always running under the minimum loss state. The results of the simulation and experiment proved the effectiveness of the efficiency of optimization control based on PSO algorithm.
