Video lecture:

Finn Haugen

15. March 2009

This video (25 minutes) demonstrates which parameter changes in a feedback control system (i.e. control loop) that can cause the control system to become unstable.

The video is based on the simulator levelcontrol_chiptank.exe. (You can run the simulator while watching the video.) Information about this simulator is available here.

The software needed to run the simulator is described here.
