Non-fragile H∞ control for networked control systems with quantization and time-delays

This paper studies the non-fragile H_∞ control problem for Networked Control Systems (NCSs) with quantization and time-delays. The controller to be designed is assumed to have additive gain variations of interval type. A new approach in terms of a set of linear matrix inequalities has been developed to deal with the problem. The designed controller ensures the networked control system to be asymptotically stable and guarantees the H_∞ attenuation level less than a prescribed level. A numerical example confirms the validity of the resulting design.
