This course focuses on the fundamental principles of control theory and the practice of automatic process control. The basic concepts involved in process control are then introduced, including the elements of control systems, feedback/forward control, block diagrams, and transfer functions. The mathematical techniques required for the analysis of process control are covered, focussing on Laplace Transform analysis. Development to more general situations is made through the study of second order systems and the application of compensation including PID control. The control theory developed is applied to a range of chemical engineering problems using simulation tools.
