A novel delay-dependent asymptotic stability conditions for differential and Riemann-Liouville fractional differential neutral systems with constant delays and nonlinear perturbation
The novel delay-dependent asymptotic stability of a differential and Riemann-Liouville fractional differential neutral system with constant delays and nonlinear perturbation is studied. We describe the new asymptotic stability criterion in the form of linear matrix inequalities (LMIs), using the application of zero equations, model transformation and other inequalities. Then we show the new delay-dependent asymptotic stability criterion of a differential and Riemann-Liouville fractional differential neutral system with constant delays. Furthermore, we not only present the improved delay-dependent asymptotic stability criterion of a differential and Riemann-Liouville fractional differential neutral system with single constant delay but also the new delay-dependent
asymptotic stability criterion of a differential and Riemann-Liouville fractional differential neutral equation with constant delays. Numerical examples are exploited to represent the improvement and capability of results over another research as compared with the least upper bounds of delay and nonlinear perturbation.This work is supported by Science Achievement Scholarship of Thailand (SAST), Research and

On the Nonlinear Impulsive --Hilfer Fractional Differential Equations
In this paper, we consider the nonlinear -Hilfer impulsive fractional
differential equation. Our main objective is to derive the formula for the
solution and examine the existence and uniqueness of results. The acquired
results are extended to the nonlocal -Hilfer impulsive fractional
differential equation. We gave an applications to the outcomes we procured.
Further, examples are provided in support of the results we got.Comment: 2
Fractional Order Version of the HJB Equation
We consider an extension of the well-known Hamilton-Jacobi-Bellman (HJB)
equation for fractional order dynamical systems in which a generalized
performance index is considered for the related optimal control problem. Owing
to the nonlocality of the fractional order operators, the classical HJB
equation, in the usual form, does not hold true for fractional problems.
Effectiveness of the proposed technique is illustrated through a numerical
example.Comment: This is a preprint of a paper whose final and definite form is with

Generalized Mittag-Leffler stability of fractional impulsive differential system
This paper establishes sufficient conditions for Generalized Mittag-Leffler
stability of a class of impulsive fractional differential system with Hilfer
order. The analysis extends through both, instantaneous and non-instantaneous
impulsive conditions. The theory utilizes continuous Lyapunov functions, to
ascertain the stability conditions. An example is given discussing for various
ranges
Practical stability for fractional impulsive control systems with noninstantaneous impulses on networks
This paper investigates practical stability for a class of fractional-order impulsive control coupled systems with noninstantaneous impulses on networks. Using graph theory and Lyapunov method, new criteria for practical stability, uniform practical stability as well as practical asymptotic stability are established. In this paper, we extend graph theory to fractional-order system via piecewise Lyapunov-like functions in each vertex system to construct global Lyapunov-like functions. Our results are generalization of some known results of practical stability in the literature and provide a new method of impulsive control law for impulsive control systems with noninstantaneous impulses. Examples are given to illustrate the effectiveness of our result
