Objectives of the Chapter
The overall objective is to present the basic concepts for determining a process model from empirical tests conducted on the plant. Specific topics to be discussed include
The identification problem.
The least-squares formulation and solution.
Chapter 14, “Discrete-Time Models”
Appendix C, “Linear Least-squares Regression”
Appendix D, “Random Variables and Random Processes”
Identification is used to describe the process of determining a process model from empirical test data collected from a process. In Chapter 2 we discussed the step test method used by process engineers to estimate parameters for an FOPDT (first-order plus dead ...
