Abstract

This paper studies the robust control problem of a class of Networked Predictive Nonlinear Control Systems (NPNCS), where the nonlinear process is linearisable and contains non-vanishing perturbations. The robust control of the NPNCS is considered. An event-driven networked predictive controller is applied to stabilise the system. A method is developed to study the stability of the closedloop unperturbed system by formulating the problem as a sub-optimal problem constrained by a series of inequalities. This method is also generalised to the robust stability analysis of the perturbed NPNCSs. The efficiency of the control scheme is illustrated using a numerical example.
