交流伺服系统的H∞鲁棒控制研究

摘要

本文介绍了一种基于H∞理论的控制方法，并将其应用于对交流伺服电机转速鲁棒控制的研究，理论分析和仿真实验结果证明了该算法具有良好的跟踪特性和对系统参数摄动的鲁棒性。%In this paper, a control method based on H∞ control theories hasbeen introduced and applied into the robust control on the speed control of AC servo system. The results of theoretical analysis and the simulation experiments have proved that the control algorithm has the good tracing characters and robust characters on the parametric uncertainty.
