Abstract

A new conditioning dual-rate observer-based tracker for a hybrid chaotic system with saturating actuator is newly proposed in this paper. This includes the following features: (1) The optimal linearization approach of non-linear chaotic system is presented. (2) The digitally redesigned predictive observer-based tracker is newly developed to track a periodic orbit embedded within the attractor of the Chen's chaotic system. (3) An inner-state compensator is added to account for the wind-up phenomenon. (4) The designed scheme can easily be implemented using digital processors and enable us to improve the performance of chaotic system with saturating actuators The illustrative examples are presented to demonstrate the effectiveness of the proposed procedure.
