Título: An Introduction to fault Diagnosis Systems with Application to Aircraft Turbine Engines and Wind Turbines”

Resumo:

Fault diagnosis systems, also called condition monitoring systems, provide on-line information on the
state of health of a device or a process. They aim at detecting small degradations, so that
maintenance operations can be planned in due time, before the faults lead to process shut down. In
this seminar, the typical structure of a fault diagnosis system will be introduced. It is made of two
parts: a residual generator and a decision system. The first aims at generating fault indicators (also
called residuals) from the measurement recorded on-line. The second processes the residual signals
in order to provide a list of the most likely fault(s), if any. Next the principle of a design method for
both parts will be presented. The methodology will then be illustrated on two applications, namely
leak detection in the lubrication system of an aircraft turbine engine, and sensor monitoring in wind
driven doubly fed induction generators.

Cronograma de atividades:

Terça-feira (5/11/2013) – às 16h00

Conferência 1: Interactividad en Control Automático: Fundamentos y experiencias.

Abstract:

The first part of this lecture presents the concepts of interactivity and visualization and its essential role in learning the fundamentals and techniques of automatic control. More than 10 years of experience of the author in the development and design of interactive tools dedicated to the study of automatic control concepts are also exposed. The second part of the paper summarizes the main features of the “Automatic Control with Interactive Tools” text that has been recently published by Pearson and whose aim is to provide a series of auto-contained tools allowing to learn different basic concepts related to the automatic control. The work has been focused on how to represent the main concepts and how to formulate them according to learning based on examples.

Quinta-feira (07/11/2013) – às 10h00

Conferência 2: Desarrollo de Laboratorios virtuales/remotos en Ciencias e Ingenieria

Abstract:

This lecture describes the latest developments carried out in the UNEDLabs Portal (http://unedlabs.dia.uned.es/) which is a network of collaborative virtual and remote Laboratories developed by the Department of Computer Science and Automatic Control of the Technical School of Computer Engineering at UNED. After a brief introduction to the concept and fundamentals of virtual and remote laboratories a panoramic overview of all developments made by the group in the past will be shown. Finally some new laboratories that have been put in place, in the last year will be presented in order to show how an end user can publish new labs in the UNEDLabs Portal.

Quinta-feira (07/11/2013) – às 11h00

Conferência 3: Fundamentos de Control baseado en Eventos.

Abstract:

Most research in control engineering considers periodic or time-driven control systems. Event based control is particularly a very promising alternative when systems with reduced computation and communication capacities are considered. For event-driven controllers it is the occurrence of an event, instead of the autonomous progression of time what decides when the sampling should be made. This lecture presents an overview of the current situation of event based control systems. The main based event sampling schemes are described and the different strategies of control design using this sampling type are analysed. In particular the important case of event based PID control will be considered.

As palestras serão realizadas nas Salas de Aula do PPGEAS.
