Adaptive fuzzy tracking control for non‐strict‐feedback non‐linear systems with non‐constant delays and full state constraints

open access: yesIET Control Theory &Applications, Volume 16, Issue 14, Page 1383-1395, September 2022., 2022
Abstract This paper aims at the tracking control problem of the non‐strict‐feedback non‐linear systems with non‐constant unknown delays and full state constraints. A constrained exponential Lyapunov–Krasovskii function‐based fuzzy adaptive dynamic surface control (CELK‐FADSC) method is proposed.

Razumikhin-type theorems for impulsive differential equations with piecewise constant argument of generalized type

open access: yesAdvances in Difference Equations, 2018
In this paper, we focus on developing Razumikhin technique for stability analysis of impulsive differential equations with piecewise constant argument. Based on the Lyapunov–Razumikhin method and impulsive control theory, we obtain some Razumikhin-type ...

Razumikhin technique for boundedness of the solutions of impulsive integrodifferential equations

open access: yesMathematical and Computer Modelling, 2001
The authors consider the problem of uniform boundedness of solutions of integrodifferential equations. The Razumikhin technique using piecewise continuous Lyapunov functions is applied. They obtain sufficient conditions significantly depending on the moments of impulses.

Robust fuzzy model predictive control for voltage regulation in islanded microgrids

open access: yesIET Generation, Transmission &Distribution, Volume 16, Issue 5, Page 1013-1029, March 2022., 2022
Abstract An effective robust fuzzy model predictive control (RFMPC) method for secondary voltage control in islanded microgrids (μGs) is presented here. In contrast to the existing techniques, which require a detailed model of μG and an ideal communication network between μG central controller and primary local controllers, RFMPC is synthesized for a ...

Input‐to‐State Stability Analysis for Stochastic Mixed Time‐Delayed Neural Networks with Hybrid Impulses

open access: yesMathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
This paper investigates the mean‐square exponential input‐to‐state stability (MEISS) of stochastic mixed time‐delayed neural networks with hybrid impulses. A generalized comparison principle is introduced and a new inequality about the solution of an impulsive differential equation is established.

Stability of delayed switched systems via Razumikhin technique and application to switched neural networks

open access: yesIMA Journal of Mathematical Control and Information, 2020
Abstract This paper investigates the globally exponential stability of delayed switched systems via Razumikhin technique. According to mode-dependent dwell average time and multiple Lyapunov functions, new Razumikhin-type stability results are deduced.

Combining Augmented Error Modeling Technique and Block‐Pulse Functions Method for Tracking Control Design of Nonlinear Polynomial Systems with Multiple Time‐Delayed States Subject to Nonsymmetric Input Saturation

open access: yesMathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
The present research work is intended to synthesize a novel tracking control strategy for a class of nonlinear polynomial systems characterized by multiple well‐defined delays in state variables under the presence of nonsymmetric input saturation. The design strategy makes full use of an associate’s memory nonlinear state feedback control with integral‐

Stability Analysis of Stochastic Nonlinear Systems With Delayed Impulses and Markovian Switching

open access: yesIEEE Access, 2019
In this paper, we are concerned with the stability analysis of stochastic nonlinear systems with delayed impulses and Markovian switching. Different from the previous literature, the impulses in this paper depend on delays and the jumping parameters are ...
