On the Model-Based Approach to Nonlinear Networked Control Systems

The problem of model-based stabilization of a nonlinear system based on its approximate discrete-time model is addressed under the assumption that both the feedforward and the feedback paths are subject to network induced constraints. These constraints include irregularity of the transfer intervals, time-varying communication delays, and possibility of packet losses. A communication protocol that copes with these constraints is proposed. "Stability+performance recovery" result for the nonlinear model-based NCS is presented. Simulation results demonstrate that the proposed method improves the maximum allowable transfer interval.
