SignForce

Constant force changing sign with speed

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Model of constant force which changes sign with direction of movement.

Please note:
Positive force accelerates in both directions of movement.
Negative force brakes in both directions of movement.

Around zero speed regularization avoids numerical problems.
