This paper focuses on the non-fragile guaranteed cost control problem for a class of TakagiSugeno (T-S) fuzzy time-varying delay systems with local bilinear models and different state and input delays. A non-fragile guaranteed cost state-feedback controller is designed such that the closed-loop T-S fuzzy local bilinear control system is delay-dependent asymptotically stable, and the closed-loop...

The paper is concerned with robust H∞ non-fragile controller design for uncertain descriptor systems with time-delay. A descriptor system has potential to describe a wide class of physical systems. It can give a representation of the system with algebraic constraints. A unique characteristic of descriptor systems is possible impulse modes and nonregularity, which do not appear in state-space sy...

Abstract The purpose of this article is to solve the fragile problem prescribed performance control (PPC) with application Waverider Vehicles (WVs). By problem, it denotes that tracking errors may break away from funnels if actuators are saturated. Firstly, we propose a new type readjusting which adaptively readjusts its such spurred transient and steady-state still guaranteed for in presence a...

This paper is concerned with the non-fragile H∞ control problem for a class of discrete-time systems subject to randomly occurring gain variations (ROGVs), channel fadings and infinite-distributed delays. A new stochastic phenomenon (ROGVs), which is governed by a sequence of random variables with a certain probabilistic distribution, is put forward to better reflect the reality of the randomly...

Blade Pitch Controller (BPC) that can cope system uncertainties is one of the most interesting topics in wind energy engineering. Therefore, this paper presents a step towards the design of robust nonfragile BPC for wind energy conversion system. The proposed approach presents all boundaries of stability region that can guarantee robust stability (RS) over a wide range of operating conditions. ...

The paper deals with the synthesis of a non-fragile state controller with reduced design complexity for a class of continuous-time nonlinear delayed symmetric composite systems. Additive controller gain perturbations are considered. Both subsystems and interconnections include time-delays. A low-order control design system is first constructed. Then, stabilizing controllers with norm bounded ga...

This paper considers the synthesis of non-fragile H∞ state feedback controllers for singular systems and static state feedback controller with multiplicative uncertainty. The sufficient condition of controller existence, the design method of non-fragile H∞ controller, and the measure of non-fragility in controller are presented via LMI(linear matrix inequality) technique. Also, through singular...
