Abstract :
Analyses a linear discrete-time system controlled by a state-space predictive controller. It is assumed that the parameters and the dynamic order of the system used for the design of the controller differ from the true parameters of the plant. For such a system, the steady state output predictions are calculated. Subsequently, it is shown that the steady-state tracking error is zero. Some generalisations of this result are also discussed
