本文在详细分析感应电动机损耗的基础上，提出了一种在线效率优化控制器。控制器通过控制变量的连续变化来搜索最小电动机驱动输入功率，从而导致平滑的系统性能，这是通过控制变量的常规逐步变化所不可能的。搜索时间很短。因此，该控制器可以有效地应用于速度和负载频繁变化的应用。此外，在所提出的控制器下，实现了更多的节能。广泛的仿真进行了建议和传统的效率优化控制器下的感应电动机。仿真结果证明了该控制器的优越性。
In this paper, an on-line efficiency optimization controller is proposed for induction motor drives after a detailed analysis of motor losses. The controller searches for a minimum motor drive input power by continuous variation of a control variable, resulting in a smooth system performance, which is not possible by the conventional stepwise change of the control variable. The search period is short. Thus, the controller can be applied effectively to applications with frequent changes of speed and load. Also, under the proposed controller, more energy saving is achieved. Extensive simulation is performed for the induction motor under the proposed and conventional efficiency optimization controllers. The results prove the superiority of the proposed controller.
