PCA demonstration example

PCA application example on statistical process control

This file is used to explain how PCA works and the idea behind the method. This example is given in the ISA book: New directions in Bioprocess Modeling and Control by Michael A. Boudreau and Gregory K. McMillan(Chapter 8, simple example). The process is composed of a valve a thermometer and a fermenter. The valve is used to control the flow rate of cooling water. The thermometer is used to measure the temperature of the fermenter. The steady state of the system is: valve=10% max. Temperature T=25 D.
