Assignments & Problem Sets
ILC Data Link
You can access many measurement points from the HVAC system of the university, notably Dupuis Hall and the Integrated Learning Centre, using the link below. These points are a good source of time series (we examined the temperature series and saw that it is periodic). Measurement points are available for temperatures, pressures, flows, actuator positions, and power consumptions. They are a good source of time series. Some will be open-loop, while others will represent closed-loop data.

I have provided a few photos below of some of the measurement points.

Dataset file for Question 1
- as a .mat file - cstr.mat
- version for Matlab v6 - cstrv6.mat
(load into Matlab using "load -ascii" or just "load" )
-
The data will be loaded as a matrix consisting of 4 columns. The first column contains the time values, the second the coolant flowrate (input), the third is the reactor concentration, and the fourth is the reactor temperature. To extract a column and name it to another variable, you can use the : notation. For example, to get the coolant flowrate -- u = cstr(:,2)
which will extract the second column of the cstr matrix, and assign it to the variable "u".

Old Final Exams
CHEE825
The course has previously been offered five times. Again, please note that the material covered has varied from year to year, particularly with respect to spectral analysis.
CHEE436
Note - the CHEE436 version was only offered in 2000 and 2001, and I have posted the exams from these years. The CHEE825 section contains exams from 1997, 1998, 2000 and 2001. The CHEE436 exams were subsets of the CHEE825 exams, and thus you may find some parts of the 825 exams useful as well. Also, please note that the material covered varied from year to year (particularly with respect to input signal design and spectral analysis).
