Decentralized Output Feedback Control using Sparsity Invariance with Application to Synchronization at European XFEL
In this work, we apply the recent framework of sparsity invariance to a large-scale facility, the European XFEL. With the sparsity invariance framework, the most general known class of convex approximations of distributed controller design problems is characterized. It is shown in previous work that this convex restriction can perform at least as well as all existing approximations for the possibly NP-hard problem of distributed controller design.
