Decentralized output feedback control of a class of large-scale interconnected systems Academic Article

abstract

• The focus of the research is on the design of a decentralized output feedback controller for a class of large-scale systems using linear matrix inequalities (LMIs). The class of large-scale systems is characterized by unmatched non-linear interconnection functions that are uncertain but quadratically bounded in the overall system state. An elegant LMI solution to the problem was given in Siljak & Stipanovic (2001, Autonomous decentralized control. Proceedings of the International Mechanical Engineering Congress and Exposition. Nashville, TN), but the method requires that the input matrix of each subsystem be invertible, i.e. each subsystem has as many independent control inputs as state variables. We provide an LMI solution that does not require invertibility of the input matrix of each subsystem. Simulation results on an example are given to validate the design. 2007 Oxford University Press.
