Cyber-Physical Systems

The assignments have now been corrected. You can find your points and individual feedback on your personal page.

As communicated in the lecture, you needed 12.5 out of 25 points to pass the assignment.

If your submission included a controller, you should also be able to download a short video showing the pendulum running with your controller (the swing up phase is done before your controller kicks in, and when the pendulum is in the upright position your designed controller takes over).

It was great to see that some submissions successfully stabilized the pendulum. The resulting videos show quite a range of behaviours: in some cases the pendulum stays upright while the base is spinning very fast, in others it is somewhat jittery but kept more or less in position, and in some cases the stabilization is quite good. Then there are also many videos where the pendulum simply spins wildly without ever reaching a stable behavior.

Please note that the assigned points are not based on the qualitative behaviour shown in these videos. In particular, the assignment did not take robustness or visual smoothness of the controller into account. The videos are provided as additional feedback and as an illustration of how your controller behaved in simulation and as motivation for what we are studying in the second part of the course.

The assignment release date is 11.05.2026 00:01 (you will find the PDF with the assignment description in the Materials page here in CMS). You will be able to submit your solution (a zip file containing code and a pdf) until 17.05.2026 23:59. No deadline extension will be allowed. Submitting and passing the assignment is mandatory for exam participation.
