Abstract :
This paper introduces a novel approach to BIBO stability of NARX control systems. The approach is based on difference inequalities and assumes availability of an approximate NARX model and the system order. For the class of bounded inputs sufficient conditions for BIBO stability are given and shown practicable. They also allow designing a controller using the model, leading to BIBO stable closed-loop system.
