Modelling and Learning for Dynamical Systems (TSRT92)
Lab 2 - Identification
The aim with this lab is to build a reliable model for a weather vane using system identification techniques.
- The lab instructions can be found here.
Report and review submissions are done through Lisam.
This involves, among other things:
- Experiment design (e.g. choose suitable input and sampling frequency)
- Carry out the experiment and collect data from the system
- Preprocessing data (remove trends and
outliers
, filtering, etc.) - Model structure selection
- Model validation
Instructions:
Most of the lab will be carried out on your own time, in groups of two.
1. Data collection
During two scheduled hours you will collect data from the actual process (weather vane) in Laboteket (B-building, entr. 27, C-corridor). A lab assistant will be present to give some information and answer any questions you have regarding the lab. Don't forget to sign up for the lab!
2. Independent work
After data collection, you will identify a suitable model of the weather vane with help from the Matlab System Identification Toolbox (available in Laboteket and ISY's computer rooms, as well as on your own computer if downloaded from Studentportalen).
You will have access to Laboteket during the course (when there is no scheduled lab) and can perform further data collection on your own if necessary. You are welcome to contact the teaching assistants if you have any further questions.
3. Lab report
A written lab report describing your results should be submitted through Lisam. The report should be well written and conclusions clearly motivated. Reports written in Swedish or English are accepted. Make sure to write name, personnummer and LiU-ID on the cover page.
Deadline: One week after your data collection lab.
4. Peer review
Your group will be assigned a report to review.
Deadline: See Lisam.
5. Final lab report
Read comments by reviewers and make adjustments accordingly. Furthermore, write a brief (max. one page) Response to Reviewers, where you outline the changes made (and why) to the report and put this after the cover page. Make sure to write name, personnummer and LiU-ID on the cover page.
Deadline: See Lisam.
