The measurement errors are dealt with by set-valued maps in the recursive control design of the subsystems. With appropriately designed decentralized controllers, the subsystems are rendered input-to-state stable (ISS) with respect to the outputs of the other subsystems and the disturbances. The robust stability of the closed-loop decentralized system is guaranteed by a recently developed cyclic-small-gain theorem.Keywords: Input-to-state stability; Large-scale nonlinear systems; Output feedback; Sensor noise; Small gain; Decentralized control; Robustness (control systems); Sensors; Feedback control Decentralized control; Input-to-state stability (ISS); Large-scale nonlinear systems; Output feedback; Sensor noise; Small-gain201110.3182/20110828-6-IT-1002.016982016-02-24
