Interactive System Identification: Prospects and Pitfalls (Communications and Control Engineering) - Tapa dura
Sinopsis
This book intends to provide users of identification software with the fundamental insight needed to carry out the interactive design of models of physical objects. The text begins with the fundamental conditions for setting up correct identification problems, continues by highlighting the roles of the validation and falsification of models, and concludes with concrete procedures for the interactive design of stochastic dynamic models. The book does not concentrate on the usual blackbox models. It emphasizes the purpose of the design and the importance of supplementing experimental data with the partial knowledge that is often available to the designer. The book also emphasizes the prospects and limitations of identification. It clarifies what can and cannot be inferred about the object under various circumstances, and, consequently, what kind of modelling errors the computer can and cannot diagnose.

Reseña del editor
The craft of designing mathematical models of dynamic objects offers a large number of methods to solve subproblems in the design, typically parameter estimation, order determination, validation, model reduc tion, analysis of identifiability, sensi tivi ty and accuracy. There is also a substantial amount of process identification software available. A typi cal 'identification package' consists of program modules that implement selections of solution methods, coordinated by supervising programs, communication, and presentation handling file administration, operator of results. It is to be run 'interactively', typically on a designer's 'work station' . However, it is generally not obvious how to do that. Using interactive identification packages necessarily leaves to the user to decide on quite a number of specifications, including which model structure to use, which subproblems to be solved in each particular case, and in what or der. The designer is faced with the task of setting up cases on the work station, based on apriori knowledge about the actual physical object, the experiment conditions, and the purpose of the identification. In doing so, he/she will have to cope with two basic difficulties: 1) The com puter will be unable to solve most of the tentative identification cases, so the latter will first have to be form11lated in a way the computer can handle, and, worse, 2) even in cases where the computer can actually produce a model, the latter will not necessarily be valid for the intended purpose.
