Decentralized Quantized Control


In this chapter, we examine the problem of decentralized quantized feedback stabilization for a class of linear interconnected systems. Both continuous-time and discrete-time systems are treated. In either case, the system has unknown-but-bounded couplings and interval delays. Two approaches have been addressed: the first approach incorporates typical quantizers (like uniform-type or logarithmic-type) and the second approach provides a generalized setting where the quantizer has arbitrary form that satisfies a quadratic inequality constraint. A decentralized quantized output-feedback controller is designed at the subsystem level to render the closed-loop system is delay-dependent asymptotically stable with guaranteed γ-level. Several special cases of interest are derived. We illustrate the theoretical developments by numerical simulations.
