H∞ Robust Predictive Control for Networked Control Systems with Time Delays

The H∞ robust state feedback predictive controllers design problem is investigated in this paper for a class of
networked control systems (NCSs) with uncertain long delays, disturbance and input constraints. Sufficient conditions for the closed-loop networked control system (NCS) to be asymptotically stable and the robust performance index to be upper bounded are derived by using the receding optimization principle. Design procedure for the state feedback controllers is also presented. Finally, an example is given to demonstrate the effectiveness of the proposed method.
