Subject Description

The objective of this unit is to introduce methods of process control where conventional feedback control is likely to be inadequate. Topics covered include:

Control of processes with inverse response or significant dead time, dead time and inverse response compensation. Comparison of feedforward and feedback control, ideal, steady-state and lead-lag feedforward compensation, tuning of lead-lag compensator. Computer as a PID controller, computer as a lead-lag element, computer based supervisory control; structure of computer based control system, sampling time and Shannon sampling theorem. Interactions in multiple-input multiple-out (MIMO) processes, steady-state analysis of MIMO processes, Bristol relative gain arrays, steady-state decoupling. Introduction to model-based control, dynamic matrix control.
