Abstract :
This paper introduces a novel approach to evaluation of modelling error of NARX control systems. The approach is based on difference inequalities and assumes availability of an approximate NARX model and the system order. Sufficient conditions for modelling error are derived ensuring boundedness of the error between model´s and plant´s outputs for the same inputs.
