This work presents a mathematical model of homeostasis dynamics in healthy individuals, focusing on the generation of conductive data on glucose homeostasis throughout the day under dietary and physical activity factors. Two case studies on glucose dynamics for populations under conditions of physical activity and sedentary lifestyle were developed...
Article
This article presents a novel observer synthesis for nonuniform observable uncertain nonlinear systems with sampled (constant and non-uniform intervals) and disturbed delayed output. An observer with a cascade structure is proposed in order to obtain (in a continuous way) the estimated free-delay state vector. The base of the cascade structure is a...
Article
In this paper, a fault-tolerant control scheme is presented for a boiler-turbine unit of a thermal power plant covering a wide range of operations: at low, medium, and high loads. The approach is based on the use of an observer-based actuator fault estimation system to detect and estimate the fault magnitude for a posteriori compensation via a faul...
Article
This article presents a generalized learning observer (GLO) design for the simultaneous estimation of states and actuator faults for polytopic quasi‐linear parameter varying systems. The proposed approach is based on the use of a GLO, which generalized the existing results on the proportional‐integral observers. Conditions of existence and stabilit...
Conference Paper
Full-text available
In this work, a full-state observer is presented for non-uniform observable nonlinear systems in presence of uncertainties and delayed output. The observer has a cascade structure, which is based on a high-gain observer that estimates the delayed state. Subsequently, the cascade structure has m subsystems, each one estimating a part of the total de...

In this paper, a design of an adaptive observer for linear parameter varying (LPV) systems is proposed. This observer must be able to estimate simultaneously states and parameters. The estimated parameter vector is used to compute the scheduling functions and thus interpolate the local linear models. Its conditions of existence and stability are gi...

This study concerns the observer design for Lipschitz non‐linear descriptor systems. It introduces a new observer structure called a generalised dynamic observer, which is more general than the proportional and proportional–integral observers. The originality of the proposed observer is that it provides additional degrees of freedom in the observer...

This paper presents a new approach to H∞ observer design for a class of nonlinear systems with unknown inputs. The considered systems are composed of a linear part perturbed by an additive Lipschitz nonlinearity in the presence of unknown inputs and disturbances. Our objective is to present a dynamical observer which generalises the Luenberger obse...

The objective of this work is to present a Takagi–Sugeno (T-S) controller for temperature regulation in an alcoholic fermentation process. The controller gains are computed using the second Lyapunov method in order to provide closed loop stability. The starting point to design the controller is to select a non-linear mathematical model that represe...

This paper addresses the problem of H∞ observer-based control design for descriptor systems.Anewconcept of dynamical observer-based control is introduced for linear descriptor systems. The main advantage of this concept is the structure of this dynamical observer, which is more general than those founded in the literature. By using this general str...

An observer-based method for actuator fault estimation for descriptor systems is presented. An innovative generalised dynamic observer for descriptor systems is synthesised to perform a convergent estimation of actuator faults.

In this paper a system of fault detection and isolation (FDI) in sensors of boiler following control of a thermal power plant is presented.

Two observer design approaches for analytical redundancy are presented in this work. The first one is based on the use of Takagi—Sugeno observers, whereas the second method is based on nonlinear high-gain observers. The objective is to conduct a comparative study between these two different approaches for a posteriori application of monitoring proc...

The control reconfigurability measure defines the capability of a control system to allow recovery of performance when faults occur; therefore, it has been intended to be a tool for designing and synthesizing approaches in the fault tolerant control context. Reconfigurability depends on the controllability gramian, also known as the second-order in...

Full-text available
This paper proposes a discrete-time robust fault estimation scheme based on an interval Takagi-Sugeno Unknown Input Observer (UIO). The designed observer allows the interval estimation of states and faults by considering that the uncertainty is modelled in a deterministic bounded context. Furthermore, in the observer design, the effect of uncertain...
