The Efficiency Optimization Control of Induction Motor Based on Adaptive Backstepping Method

感应电机的最小输入功率法是一种有效的效率优化方法,该方法是在保证电动机输出性能不变的前提下,尽可能地降低电机的输入功率,从而提高电机的稳态运行效率。因此,设计了一种基于自适应反步控制器的效率优化控制方案,使其误差系统在原点全局稳定。仿真结果表明,在轻载情况下该方案不仅具有良好的转速跟踪效果,而且提高了稳态运行效率。

The minimum input power method of an induction motor is an effective method to optimize the efficiency of the motor. It is a scheme that makes the motor input power to be as reducing as possible under to assurance the throughout performance constant, thus to enhance the motor efficiency. Therefor, An adaptive backstepping controller is designed to optimize the efficiency and the system error is global stable at the origin. Simulation results show that this controller has not only better speed tracking performance but also increase the stable efficiency at low loads.
