Journal ArticleDOI

Robust H ∞ sliding mode observer design for fault estimation in a class of uncertain nonlinear systems with LMI optimization approach

TL;DR: In this paper, the Lipschitz constant of the nonlinear term in the system and the disturbance attenuation level are maximized simultaneously through convex multiobjective optimization.
Journal ArticleDOI

A novel fuzzy c-regression model algorithm using a new error measure and particle swarm optimization

TL;DR: The proposed methodology is based on adding a second regularization term in the objective function of a Fuzzy C-Regression Model (FCRM) clustering algorithm in order to take into account noisy data.
Journal ArticleDOI

An H∞ Sliding Mode Observer for Takagi-Sugeno Nonlinear Systems with Simultaneous Actuator and Sensor Faults

TL;DR: The main contribution is to develop a sliding mode observer (SMO) with two discontinuous terms to solve the problem of simultaneous faults to guarantee the stability of the state estimation error.
Journal ArticleDOI

Novel optimal recursive filter for state and fault estimation of linear stochastic systems with unknown disturbances

TL;DR: In this article, a new recursive optimal filter structure with transformation of the original system is proposed, which is based on the singular value decomposition of the direct feed-through matrix distribution of the fault which is assumed to be of arbitrary rank.
Journal ArticleDOI

Robust state and fault estimation for linear descriptor stochastic systems with disturbances: a DC motor application

TL;DR: In this article, the authors considered the problem of simultaneously estimating the state and the fault of an uncertain direct current (DC) motor in light of the unknown input filtering framework, and derived an optimal filter in order to achieve a robust descriptor state and fault estimation in the presence of parameter uncertainties.
