Abstract

In this chapter, the issues in real-time identification of continuous systems are considered. Starting with some aspects of plant model forms, measurement systems and preprocessing schemes, continuous model estimation algorithms are discussed. Further postprocessing techniques for the parameter estimates and residuals which may be necessary to satisfy the requirements of specific applications such as adaptive control, fault detection, condition monitoring etc. are indicated. Salient features of hardware and software important for practical implementations are also discussed briefly. A practical example of real-time parameter estimation is presented. The chapter concludes with a summarizing view and a look into the future in the light of emerging technology.
