摘要
提出了一种基于Ｈ∞范数优化的大系统分散状态反馈控制的求解方法。首先讨论了大系统分散Ｈ∞优化控制问题，然后提出了一种迭代算法。这种算法应用可行方向阵，保证了迭代过程的收敛性和闭环系统的稳定性，并使闭环系统传递矩阵的Ｈ∞．范数趋于最优值。作者还给出了１个设计算倒，说明了该方法的应用及收敛性好和实用性强的特点。
This paper provides an approach to deslgn optimal decentralized state feedback controlbased on H∞ theory in large scale systems,It is shown that the problem of H∞-norm opti-mization under structural restrictions on the controller can be solved relatively simply.Analgorithmi;proposed which uses the method of a feasible direction matrix.The given algo-rithm provides a minimum of the H∞-norm of the closedloop transfer function matrix fromdisturbance inputs to controlled outputs while ensuring, at each iteration,he stability of theoverall controlled system The given example shows that the convergence of the algorithm isgood.
