Internal Multimodel Control for Discrete Nonlinear Systems with Time-Delay

In this paper, an internal multimodel control scheme is proposed for the control of discrete nonlinear systems with time-delay. In this framework, a decoupled polynomial multimodel is proposed for the representation of the nonlinear system. The control scheme incorporates partial internal model controls where each partial controller is associated to a specified operating zone of the nonlinear system. The switching between these controllers is ensured by a supervisor that contains a set of local predictors. A simulation example is carried out to illustrate the significance of the proposed internal multimodel control scheme.
