Abstract

A hierarchical model of chemical plants is used to explain control problems which can be solved by experimental identification. Some hints how to perform successful identification from a practical point of view for SISO and MIMO systems are given. Using a flow chart, the different steps starting with the experiment and ending with a well adjusted closed loop are explained. Advantages of parametric identification in comparision to the relay controller method which is often used by tuners integrated into DCS are shown. As an example identification and multivariable control presented a distillation column.
