摘要： 提出了一种新的鲁棒设计方法.以闭环系统矩阵的Frobenius范数作为鲁棒性指标,运用Powell方法进行寻优,产生一种适用于工程上使用的快速而有效的直接优化方法,使系统动态矩阵保持稳定的参数摄动界最大.

关键词: 鲁棒控制, 状态反馈, Powell方法

Abstract: A new robust design method is discussed in this paper. The main idea of this method is to use the addition of the pole differences and robustness measurement as a destination for optimization. It provides a quick and efficient optimizatoin method suitable for engineering.#br#Frobenius norm of the closed-loop matrix A+BK is used here as a robustness index. This index is minimized by Powell method, thus to make the lower bound of a robustness measurement maximized.

Key words: state feedback, robust control, Powell method
