Mathematical Model (Eykhoff, 1974)
“a representation of the essential aspects of an existing system (or a system to be constructed) which represents knowledge of that system in a usable form”
Everything should be made as simple as possible.

Laplace Transforms for Some Important Functions
The Inverse Laplace Transform

An alternative model form based on Laplace transforms.

In analyzing process dynamic and process control systems, it is important to know how the process responds to changes in the process inputs. A number of standard types of input changes are widely used for two reasons:
1.They are representative of the types of changes that occur in plants.
2.They are easy to analyze mathematically.
