Modelling, State Observation and Diagnosis of Quantised Systems / Edition 1

by Jochen Schröder

Overview

Ongoing advances in science and engineering enable mankind to design and operate increasingly sophisticated systems. Both their design and operation require the understanding of the system and its interaction with the envir- ment. This necessitates the formalisation of the knowledge about the system by models. A major issue is what kind of model is best suited for a given task. This book is about the supervision of continuous dynamical systems. Such systems are typically described by differential equations. However, this does not automatically mean that diffierential equations are proper models for so- ing supervision tasks. Instead, this book and recent approaches in literature show that supervision tasks do in general not require the use of such precise models as differential equations. This is of interest because uncertainties, t- ically occurring in supervision, make the use of precise models very difficult. Alternative approaches therefore use less precise models such as discrete– event descriptions to solve supervision tasks on a higher level of abstraction. Discrete–event descriptions in form of automata are one of the key elements of this book. To reach this higher level of abstraction, uncertainties by qu- tisation are introduced on purpose, taking into account a loss of precision. This is one of the main difierence to other approaches. When using nume- cal models like transfer functions or differential equations, uncertainties make the analysis more difficult. Not so here, where the system is described on a qualitative level on which uncertainties are naturally incorporated. The book presents a new way to describe systems for supervision. Preparing this book I learned that the key to solve supervision problems is simplicity.
