Robust Fractional-Order Proportional-Integral Observer for Synchronization of Chaotic Fractional-Order Systems

引用

IEEE/CAA Journal of Automatica Sinica 2019年第1期6卷 268-277页

作者： Ibrahima n’Doye khaled nabil salama Taous-Meriem Laleg-Kirati IEEE Computer Electrical and Mathematical Sciences and Engineering Division (CEMSE)King Abdullah University of Science and Technology (KAUST)

In this paper, we propose a robust fractional-order proportional-integral(FOPI) observer for the synchronization of nonlinear fractional-order chaotic systems. The convergence of the observer is proved, and sufficient conditions are derived in terms of linear matrix inequalities(LMIs) approach by using an indirect Lyapunov method. The proposed FOPI observer is robust against Lipschitz additive nonlinear uncertainty. It is also compared to the fractional-order proportional(FOP) observer and its performance is illustrated through simulations done on the fractional-order chaotic Lorenz system.
