چکیده

In this technical report, the problem of Simultaneous Fault Detection and Control (SFDC) is considered. This problem is reduced to a multiobjective optimization problem. We show that there exists a fundamental separation theorem allowing us to seperate this multiobjective problem into a control problem and a fault detection problem. Moreover, the SFDC problem is modeled in terms of a mixed optimization problem and a Riccati equation based solution leading to the design of controller/detector system of reasonable complexity is given. An application of our results is presented using the nonlinear Ball and Beam system.

Ce problème est réduit à un problème d’optimisation multi-objectifs. Nous montrons qu’il existe un théorème fondamental de séparation, qui nous permet la décomposition de ce problème multi-objectifs en un problème de commande et un problème de détection de défaut. D’ailleurs, le problème SFDC est modèle en termes de problème d’optimisation mixte et une solution de l’équation de Riccati menant à la conception d’un système détecteur/contrôleur de complexité raisonnable. Une application de nos résultats est pressée en utilisant un système nonlinéaire Ball & Beam.

Design of an Active Approach for Detection, Estimation and Short-Circuit Stator Fault Tolerant Control in Induction Motors

Three phase induction motors have many applications in industries. Consequently, detecting and estimating the fault and compensate it in a way that the faulty induction motor satisfies the predefined goals are important issues. One of the most common faults in induction motors is the short circuit of the stator winding. In this paper, an active fault-tolerant control system is designed and pres...

Application of Decision on Beliefs for Fault Detection in uni-variate Statistical Process Control

In this research, the decision on belief (DOB) approach was employed to analyze and classify the states of uni-variate quality control systems. The concept of DOB and its application in decision making problems were introduced, and then a methodology for modeling a statistical quality control problem by DOB approach was discussed. For this iterative approach, the belief for a system being out-...

Detection of Single and Dual Incipient Process Faults Using an Improved Artificial Neural Network

Changes in the physicochemical conditions of process unit, even under control, may lead to what are generically referred to as faults. The cognition of causes is very important, because the system can be diagnosed and fault tolerated. In this article, we discuss and propose an artificial neural network that can detect the incipient and gradual faults either individually or mutually. The mai...

Nonlinear and Non-stationary Vibration Analysis for Mechanical Fault Detection by Using EMD-FFT Method

The Hilbert-Huang transform (HHT) is a powerful method for nonlinear and non-stationary vibrations analysis. This approach consists of two basic parts of empirical mode decomposition (EMD) and Hilbert spectral analysis (HSA). To achieve the reliable results, Bedrosian and Nuttall theorems should be satisfied. Otherwise, the phase and amplitude functions are mixed together and consequently, the ...
