Abstract

Modeling and control of networked feedback systems are studied in this paper. Motivated by the two-port circuit theory, new network models are proposed which take inter-channel interference into consideration. Quadratic stability and stabilization are employed to study stability of the closed-loop system over the networked channel leading to the framework of H_∞ control. This paper will focus on formulation for networked stabilization in presence of the uncertainties induced by imperfect channels and quantization errors.
