Abstract
Purpose
The purpose of this paper is to investigate the stabilization of unstable periodic orbits of Chua’s system using adaptive fuzzy sliding mode controllers with moving surface.
Design/methodology/approach
For this aim, the sliding mode controller and fuzzy systems are combined to achieve the stabilization. Then, the authors propose a moving sliding surface to improve robustness against uncertainties during the reaching phase, parameter variations and extraneous disturbances.
Findings
Afterward, the authors design a sliding observer to estimate the unmeasurable states which are used in the previously designed controller.
Originality/value
Numerical results are provided to show the effectiveness and robustness of the proposed method.
