Bode shaping-based design methods of a fractional order PID controller for uncertain systems
TL;DR: In this paper, three frequency-domain design methods are proposed to deal with robust fractional order PID controller design via numerical optimization, which achieve robustness to the variation of some parameters by maintaining the open-loop phase quasi-constant in a pre-specified frequency band.
Journal ArticleDOI
New consistent methods for order and coefficient estimation of continuous-time errors-in-variables fractional models
Manel Chetoui,Manel Chetoui,Magalie Thomassin,Magalie Thomassin,Rachid Malti,Mohamed Aoun,Slaheddine Najar,Mohamed Naceur Abdelkrim,Alain Oustaloup +8 more
TL;DR: New consistent methods for order and coefficient estimation of continuous-time systems by errors-in-variables fractional models are presented and two estimators based on Higher-Order Statistics (third-order cumulants) are developed.
Journal ArticleDOI
Fault detection based on fractional order models: Application to diagnosis of thermal systems
Asma Aribi,Christophe Farges,Mohamed Aoun,Pierre Melchior,Slaheddine Najar,Mohamed Naceur Abdelkrim +5 more
TL;DR: Two diagnosis methods initially developed for integer order models are here extended to handle fractional order models and the first one is the generalized dynamic parity space method and the second is the Luenberger diagnosis observer.
Journal ArticleDOI
Discrete fractional Kalman filter
TL;DR: This paper presents a generalization of the classical discrete time Kalman filter algorithm to the case of the fractional systems and shows a simple numerical example of linear state estimation.
Journal ArticleDOI
A constant enclosure method for validating existence and uniqueness of the solution of an initial value problem for a fractional differential equation
TL;DR: A new method for validating existence and uniqueness of the solution of an initial value problems for fractional differential equations by an algorithm selecting a stepsize and computing a priori constant enclosure of the solutions is proposed.
