REDUCED-ORDER PERFECT NONLINEAR OBSERVERS OF FRACTIONAL DESCRIPTOR DISCRETE-TIME NONLINEAR SYSTEMS

摘要

The purpose of this work is to propose and characterize fractional descriptor reduced-order perfect nonlinear observers for a class of fractional descriptor discrete-time nonlinear systems. Sufficient conditions for the existence of these observers are established. The design procedure of the observers is given and demonstrated on a numerical example. Keywords: fractional, descriptor, nonlinear, discrete-time, design, reduced-order, perfect observer.
