Dynamic scheduling and H-infinity quantized feedback stabilization for networked control systems with communication constraints

A integrated design scheme of dynamic scheduling and H-infinity quantized feedback controller for a class of networked control system with communication constraints and random time delay was proposed by using logarithm quantizers. By utilizing sector-bounded method dealed with quantization error, the quantization error was treated as uncertainties, and the NCSs was modeled as a discrete-time switched system with parameter uncertainties. The procedures for H-infinity controller design under the strategy were given to guarantee stability and robust performance of the closed-loop system. Finally a simulation example was given to illustrate effectiveness of the proposed method.
