本文给出了二次不变通信延迟模式输出反馈H2问题的一种新解。给出了满足时滞约束的所有稳定控制器的刻画,并将分散H2问题转化为一个凸模型匹配问题。主要结果表明,模型匹配问题可以简化为有限维二次规划问题。给出了一种基于向量化的递归状态空间计算最优控制器的方法。
This paper gives a new solution to the output feedback H2 problem for quadratically invariant communication delay patterns. A characterization of all stabilizing controllers satisfying the delay constraints is given and the decentralized H2 problem is cast as a convex model matching problem. The main result shows that the model matching problem can be reduced to a finite-dimensional quadratic program. A recursive state-space method for computing the optimal controller based on vectorization is given.
