Decentralized Output Feedback Control of Interconnected Systems with High-Order Nonlinearities

This paper considers the problem of global decentralized output feedback control of large-scale systems with subsystems interconnected by nonlinearities which are functions of the measurable and unmeasurable states. The distinguishing factor of this paper is that the nonlinearities are allowed to be of higher-order in these unmeasurable states, and one subsystem´s nonlinearities need not be similar to another´s.
