A NEW METHOD FOR IDENTIFICATION AND CONTROL OF NONLINEAR DYNAMIC-SYSTEMS

This paper presents a new model for nonlinear systems which consists o f two parts, a linear part and a static nonlinear output part. The lin ear part is a linear combination of the model's outputs, where the sta tic nonlinear function maps the output of the linear part to the model 's output. This model can be applied to represent a relatively large c lass of nonlinear dynamic systems with fading memory. Based on this mo del, one can directly introduce the corresponding output feedback cont rol law. The identification and control method is applied to two simul ation examples of a discrete-time system and the dynamics of a complic ated missile to demonstrate the performance and efficiency of the prop osed method.
