Nyquist App vs OLPPS Mobile App v2

In this app, you can practice the Nyquist stability criterion. With the Nyquist stability criterion, you can determine the stability of the closed loop based on the frequency response of the open loop, without explicitly calculating the poles of the closed loop. This app was developed at the Institute for Systems Theory and Automatic Control of the University of Stuttgart and accompanies the course "Einführung in die Regelungstechnik" at the University of Stuttgart. Nevertheless, the content and tasks are self-contained, and we encourage all interested in this topic to play with the app and practice the Nyquist stability criterion.
