Flowsheet Controllability Analysis

It is assumed that the reader is familiar with the basic concepts of linear systems theory. This material is covered typically in an introductory course on process dynamics and control at the undergraduate level. The subjects in that course that are prerequisite to understanding the concepts in this chapter are 

Basic linear matrix theory, linearization, complex numbers, and Laplace and Fourier transforms. Note that Section 21.1 provides some of this background material. 

Pole and zero positions in the complex plane, and their impact on the time-domain response of linear systems. 

Tuning of single-input, single-output (SISO) controllers (P, PI, and PID controllers). Note that Section 21.4 provides instruction on model-based Pl-controller tuning. 

Key concepts relating to linear process models are reviewed in the first section of the chapter. For deeper coverage, the reader is referred to the following undergraduate-level texts
