Observer-Based Controller Design for Fractional-Order Neutral-Type Systems

2020
This article is devoted to investigating how to design the observer-based controller for a type of fractional-order neutral-type systems (FONTSs) by applying the Lyapunov direct method. The feedback control system based on the observer is designed, and by solving the linear matrix inequality (LMI) feasible problems, the gains of the controller and the ...

Stability and Synchronization of a Fractional Neutral Higher-Order Neural Network System

International Journal of Nonlinear Sciences and Numerical Simulation, 2020
Abstract We discuss the stability and synchronization of some neural network systems with more than one feature. They are of higher-order, of fractional order and also involving delays of neutral type. Each one of these features presents substantial difficulties to overcome.

Controllability of switched integro‐neutral fractional delay systems over arbitrary time domain

Mathematical Methods in the Applied Sciences
In this paper, we examine various qualitative properties for some class of fractional impulsive switched integro‐neutral dynamic systems over arbitrary time domain. We establish the existence, stability, and controllability of the scrutinized models. This article is divided into three parts: The first part is concerned with the existence and uniqueness,

Controllability of Nonlinear Fractional Neutral Stochastic Dynamical Systems with Poisson Jumps

2015
This paper is concerned with the controllability of fractional neutral stochastic dynamical systems with Poisson jumps in the finite dimensional space. Sufficient conditions for controllability results are obtained by using Krasnoselskii’s fixed point theorem. The controllability Grammian matrix is defined by Mittag-Leffler matrix function.
