Essentially, system identification is an art of modelling, where appropriate choices have to be made concerning the level of approximation, given prior system's knowledge, noisy data and the final modelling objective. The system identification process is basically divided into three steps: experimental design and data collection; model structure selection and parameter estimation; and model validation, each of which is the subject of one or more parts of the text. The book contains four parts covering: ·        data-based identification - non-parametric methods for use when prior system knowledge is very limited; ·        time-invariant identification for systems with constant parameters; ·        time-varying systems identification, primarily with recursive estimation techniques; and ·        model validation methods. The book uses essentially semi-physical or grey-box modelling methods although data-based, transfer-function system descriptions are also introduced. The approach is problem-based rather than rigorously mathematical. The use of finite input-output data is demonstrated for frequency- and time-domain identification in static, dynamic, linear, nonlinear, time-invariant and time-varying systems. Simple examples are used to show readers how to perform and emulate the identification steps involved in various model applications, as control, prediction and experimental design, with more complex illustrations derived from real physical, chemical and biological applications being used to demonstrate the practical applicability of the methods described. End-of-chapter exercises (for which a downloadable instructors' Solutions Manual is available from www.springer.com/978-0-85729-521-7) will both help students to assimilate what they have learnt and make the book suitable for self-tuition by practitioners looking to brush up on modern techniques. Graduate and final-year undergraduate students will find this text to be a practical and realistic course in system identification that can be used for assessing the processes of a variety of engineering disciplines. System Identification: an Introduction will help academic instructors teaching control-related courses to give their students a good understanding of identification methods that can be used in the real world without the encumbrance of undue mathematical detail.   0aENGINEERING. 0aSYSTEMS THEORY.14aENGINEERING.24aCONTROL.24aSIGNAL, IMAGE AND SPEECH PROCESSING.24aSYSTEMS THEORY, CONTROL.24aMECHATRONICS.2 aSpringerLink (Online service)0 tSpringer eBooks08iPrinted edition:z9780857295217 0aAdvanced Textbooks in Control and Signal Processing,x1439-223240uhttp://dx.doi.org/10.1007/978-0-85729-522-4zVer el texto completo en las instalaciones del CICY
