480 Laboratory 0
In this laboratory
you have two tasks to accomplish.
-
First, you need to get
acquainted with Matlab and Simulink if you haven't used them before.
-
Next, do the laboratory
described below.
In this laboratory
you are given one sample of a thermal system. Components of the system
include the equipment listed below. The hair dryer serves as a heating
unit for the interior of the cardboard box, and temperature may be measured
using the thermocouple.

The primary goal
of this laboratory is to develop a credible
model (a mathematical model) of this dynamic
system. Click here
to see how this laboratory will be graded. Notice that your goal
includes convincing the reader of your report that the model is valid,
and your report should provide the evidence listed on the grading sheet.
-
This unit is euphemistically
referred to as the "HHSS" or Home Heating System Simulator.
-
Measure the step response
of the system - assuming that turning the system on full is a unit step
input.
-
To measure the data we
will give you a program in lab that will enable you to get temperature
data in a file.
-
Record the data and determine
the transfer function from the data.
-
Prepare a short report
for next Lab Period.
We will have a
short discussion on what a mathematical model is. We'll need to draw
on your Linear Systems background.
-
The last goal is to start
getting familiar with the IEEE-488 instrument system, and programming those
instruments in C. You can use the program that takes multiple temperature
measurements to get data for this lab, but you need to be able to write
and modify your own programs. So, when you get your data, as you
do that you can begin learning how to program the instruments in C.
