Switched Control for Local Stabilization of Discrete-time Uncertain Takagi-Sugeno Fuzzy Systems with Relaxed Estimate of the Domain of Attraction
(Ieee, 2020-01-01)
This paper addresses the local stabilization problem and the computation of invariant subsets of the domain of attraction for uncertain nonlinear discrete-time systems. The proposed procedures use Takagi-Sugeno (T-S) fuzzy ...
Damage detection in an uncertain nonlinear beam
(2017-01-01)
The present paper proposes the use of discrete time Volterra series expanded with Kautz filters for predicting the experimental response of a nonlinear beam, taking into account uncertainties that are inherent to the system. ...
Robust stabilization of uncertain nonlinear systems using differential algebraic representations
(Universidade Federal de Minas GeraisUFMG, 2017-03-20)
Regional robust stabilization for a class of uncertain MIMO nonlinear systems with parametric uncertainties is investigated. The closed-loop robust stability is achieved using linear timeinvariant state feedback control. ...

Nonlinear uncertainty model of a magnetic suspension system
(Pergamon-Elsevier Science Ltd, 2004-11)
The nonlinear identification of a nominal model as well as the uncertainty bounds of a magnetic suspension system is developed. This system has a nonsymmetric dynamic behavior; it has an undershoot but not an overshoot. ...
On the detection of a nonlinear damage in an uncertain nonlinear beam using stochastic Volterra series
(2020-07-01)
In the present work, two issues that can complicate a damage detection process are considered: the uncertainties and the intrinsically nonlinear behavior. To deal with these issues, a stochastic version of the Volterra ...
On local H∞ switched controller design for uncertain T–S fuzzy systems subject to actuator saturation with unknown membership functions
(2018-08-01)
This manuscript proposes a local H∞ switched controller design for a class of uncertain nonlinear plants described by Takagi–Sugeno (T–S) fuzzy models with unknown membership functions. The control design requires only the ...
On Robust Switched Controller Design to Minimize the Guaranteed Cost of Polynomial Fuzzy Systems
(2019-06-01)
This paper presents a robust switched controller design to minimize an upper bound of a quadratic index (guaranteed cost) based on the output and the control input of uncertain nonlinear systems described by polynomial ...
