Goals: The student should be able to:

(a) write differential equation and transfer function models of standard chemical process systems.

(b) qualitatively describe the behavior of first and second order

dynamic processes and estimate process time constants.

(c) describe the basic concepts of PID control.

(d) analyze the stability of open- and closed-loop systems

Requirements: Differential equations
