AUTOMATIC CONTROL | FRT602 |

**Aim**

The aim of the course is to give the student basic knowledge in Automatic Control

and a good understanding of basic system principles.and implentation aspects

of PLC based automation systems and analog control systems

*Knowledge and understanding*

For a passing grade the student must

- be able to describe fundamental concepts such as dynamic systems,

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.

**Contents**
