time reponses, frequency responses, feedback and stability

• be able to explain the functionality of simple controllers such as PID controllers

• be able to derive mathematical descriptions of basic physical systems.

Skills and abilities
For a passing grade the student must

• be able to construct PLC programs for simple automation tasks

• be able to design controllers for simple control tasks.
