Chapter 16. Identification: Advanced Concepts

Objectives of the Chapter

The overall objective is to present some of the advanced concepts used in process identification. Specific topics to be discussed include

  • Design of input-forcing functions.

  • Prefiltering of noise in the data.

  • Modifications to the basic least-squares method to improve model accuracy.

  • Identification of multivariable systems.

The chapter concludes with a comprehensive example that illustrates most of the ideas presented on the subject of identification.
