Decentralized output feedback control of discrete-time interconnected uncertain systems

This paper is concerned with the problem of decentralized control for a class of discrete-time interconnected uncertain dynamical systems. The uncertainties we consider in this paper are real time varying norm-bounded parametric uncertainties and unknown nonlinearities in the state and output equations as well as in the interconnections between the subsystems. Interest is focused on the design of decentralized linear dynamic output feedback controllers and we address the problems of robust stabilization and robust disturbance attenuation in an H/sub /spl infin// sense.<
