Distributed Output-Feedback Control of a Class of Nonlinear Large-Scale Systems

摘要：

　　This paper presents a cyclic-small-gain approach to distributed output-feedback control of interconnected nonlinear multi-agent systems.Through novel distributed observer and control law designs,the closed-loop multi-agent system is transformed into a large-scale system composed of input-to-output stable (IOS) subsystems,the IOS gains of which can be appropriately designed.By guaranteeing the IOS of the closed-loop multi-agent system with the recently developed cyclic-small-gain theorem,the outputs of the controlled agents can be driven to within an arbitrarily small neighborhood of the desired agreement value under bounded external disturbances.Moreover,if the system is disturbance-free,then asymptotic convergence can be achieved.Interestingly,the closed-loop distributed system is also robust to bounded time-delays of exchanged information.
