modelPositionControl
Position controlled system
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
With position control the system can be kept stable, i.e. the magnet floating below the coil, even under influence of noise added to the Hall effect sensor signal and imperfect conditions due to time discrete AD/DA. It is possible to choose different reference position trajectories and check whether the magnet can follow.
Note that the initial conditions in the three discrete controllers were picked manually to ensure equal initialization in every simulator.
