摘要
根据实际工程应用的特点,改进了H_∞状态反馈控制的算法,并给出了一种选择H_∞权矩阵的方法;以此为基础设计及研究了一种能综合控制水轮发电机组的励磁和导叶开度,集励磁调节器、调速器功能于一体的综合控制系统.结果表明,该控制器在基本不影响系统响应性能的情况下,能明显地改善系统的鲁棒性.
in this paper, the H∞ optimal design method based on state-space solution technique and the selection method of H∞ weight matrix are proposed according to engineering requirements; then a hydroelectric integrated optimal control system based on state feedback is designed.Investigation show H∞ controllers robustness is more stable than that of LQG controller for the power systems. This result is significant for practical application.
