Identification of continuous systems 

Identification of continuous systems pdf

Book Description:

Bringing together important advances in continuous system identification, this book deals with parametric and nonparametric methods. It pays special attention to the problem of retaining continuous model parameters in the estimation equations, to which all the existing techniques used in estimating discrete models may be applied. It is aimed at both the academic researcher and the control engineer in the industry. The techniques covered range from certain simple numerical or graphical methods applicable to some of the frequently encountered model forms to attractive recursive algorithms for continuous model identification suitable for real-time implementation. These include the recent methods based on orthogonal functions such as those of Walsh and Poisson moment functionals. Some techniques based on stable model adaptation principles are also presented and illustrated.
