Frequency Response

Aims

The aims of this experiment are


Theory

All the relevent theory can be found in Module 7 - Frequency Response Techniques


Procedure

There are two sections to this experiment

The first part of the experiment involves working through short exercises and answering questions on the frequency response and bode plots of a number of processes:

There are java applets available which show both the frequency response at different frequencies and also the bode plots. It is possible to use both of these when working through the questions.

The second part of the experiment is an exercise on tuning a PI controller using the Bode Plots. Five processes are given. The first three are those in the experiment Comparing Controller Tuning Methods and the last two have been taken from the experiment Further Examples on Closed Loop Tuning.
