Book Description
L'ouvrage présente les diverses méthodes de synthèse d'une loi de commande par retour d'état et celles de calcul d'un observateur lorsque l'état du système n'est pas entièrement accessible. Les systèmes considérés sont aussi bien à temps continu que discret, monovariables ou multivariables, l'accent étant surtout mis sur ces derniers. Deux approches complémentaires sont suivies : l'approche modale, où est privilégié l'aspect dynamique ; l'utilisation de méthodes d'optimisation quadratique (commande optimale LQC, filtrage optimal de Kalman, commande LQG). La dualité commande-estimation est mise à profit et prolongée jusque sur le plan mathématique. Un grand nombre d'exemples et d'exercices tous corrigés (la plupart avec l'utilisation de Matlab), concrétise l'aspect pratique de l'ouvrage. Les programmes ayant servi aux résolutions sont tous disponibles sur Internet pour téléchargement. A noter la traduction, directement dans le texte, de nombreux termes techniques en anglais et en allemand.

Book Description
This book presents the various design methods of a state-feedback control law and of an observer. The considered systems are of continuous-time and of discrete-time nature, monovariable or multivariable, the last ones being of main consideration. Three different approaches are described: • Linear design methods, with an emphasis on decoupling strategies, and a general formula for multivariable controller or observer design; • Quadratic optimization methods: Linear Quadratic Control (LQC), optimal Kalman filtering, Linear Quadratic Gaussian (LQG) control; • Linear matrix inequalities (LMIs) to solve linear and quadratic problems. The duality between control and observation is taken to advantage and extended up to the mathematical domain. A large number of exercises, all given with their detailed solutions, mostly obtained with MATLAB, reinforce and exemplify the practical orientation of this book. The programs, created by the author for their solving, are available on the Internet sites of Springer and of MathWorks for downloading. This book is targeted at students of Engineering Schools or Universities, at the Master’s level, at engineers desiring to design and implement innovative control methods, and at researchers.

Book Description
Cette troisième édition a été enrichie par l'introduction de nouveaux exemples et de méthodes récentes. En un volume unique, le livre propose une synthèse progressive et approfondie des principales méthodes de commande exposées sous forme théorique et illustrées sur des exemples variés de procédés : réacteurs chimiques, biologiques, de polymérisation, craqueur catalytique, colonne de distillation. Les six parties couvrent la modélisation et la commande continue monovariable, la commande multivariable par fonction de transfert, l'identification et la commande en temps discret, la commande optimale et prédictive multivariable, la commande non linéaire et les observateurs d'état. Cet ouvrage s'adresse aussi bien aux étudiants de 2e et 3e cycle qu'aux chercheurs, enseignants et ingénieurs.

Book Description
The foundation of linear systems theory goes back to Newton and has been followed over the years by many improvements such as linear operator theory, Laplace Transformation etc. After the World War II, feedback control theory has shown a rapid development, and standard elegant analysis and synthesis techniques have been discovered by control system workers, such as root-locus (Evans) and frequency response methods (Nyquist, Bode). These permitted a fast and efficient analysis of simple-loop control systems, but in their original "paper-and-pencil" form were not appropriate for multiple loop high-order systems. The advent of fast digital computers, together with the development of multivariable multi-loop system techniques, have eliminated these difficulties. Multivariable control theory has followed two main avenues; the optimal control approach, and the algebraic and frequency-domain control approach. An important key concept in the whole multivariable system theory is "ob servability and controllability" which revealed the exact relationships between transfer functions and the state variable representations. This has given new insight into the phenomenon of "hidden oscillations" and to the transfer function modelling of dynamic systems. The basic tool in optimal control theory is the celebrated matrix Riccati differential equation which provides the time-varying feedback gains in a linear-quadratic control system cell. Much theory presently exists for the characteristic properties and solution of this Riccati equation.

Book Description
Computer Aided Design of Multivariable Technological Systems covers the proceedings of the Second International Federation of Automatic Control (IFAC). The book reviews papers that discuss topics about the use of Computer Aided Design (CAD) in designing multivariable system, such as theoretical issues, applications, and implementations. The book tackles several topics relevant to the use of CAD in designing multivariable systems. Topics include quasi-classical approach to multivariable feedback system designs; fuzzy control for multivariable systems; root loci with multiple gain parameters; multivariable frequency domain stability criteria; and computational algorithms for pole assignment in linear multivariable systems. The text will be of great use to professionals whose work involves designing and implementing multivariable systems.

Book Description
Environmental quality is becoming an increasing concern in our society. In that context, waste and wastewater treatment, and more specifically biological wastewater treatment processes play an important role. In this book, we concentrate on the mathematical modelling of these processes. The main purpose is to provide the increasing number of professionals who are using models to design, optimise and control wastewater treatment processes with the necessary background for their activities of model building, selection and calibration. The book deals specifically with dynamic models because they allow us to describe the behaviour of treatment plants under the highly dynamic conditions that we want them to operate (e.g. Sequencing Batch Reactors) or we have to operate them (e.g. storm conditions, spills). Further extension is provided to new reactor systems for which partial differential equation descriptions are necessary to account for their distributed parameter nature (e.g. settlers, fixed bed reactors). The model building exercise is introduced as a step-wise activity that, in this book, starts from mass balancing principles. In many cases, different hypotheses and their corresponding models can be proposed for a particular process. It is therefore essential to be able to select from these candidate models in an objective manner. To this end, structure characterisation methods are introduced. Important sections of the book deal with the collection of high quality data using optimal experimental design, parameter estimation techniques for calibration and the on-line use of models in state and parameter estimators.
