A Flexible Synthesis Framework of Structured Controllers for Networked Systems
Christian A. Rösinger, Carsten W. Scherer · IEEE Transactions on Control of Network Systems · 2019
We propose a framework to synthesize a block-diagonally structured H∞-controller that consists of a parametric and a block-triangular dynamic component. Moreover, we present an application to H∞-design with controller constraints that arise from a delayed chained interconnection of subsystems that are, by themselves, described by delayed strongly connected communication graphs. We introduce a compact notation to describe the delayed graph structures and give a precise classification of all tractable network-induced constraint sets that can be handled within our framework. Furthermore, the flexibility of our approach is demonstrated through the application to a vehicle platoon with different controller communication scenarios.
