Detailed Description

Abstract base class to define a reference trajectory that the ControlLaw aims to track.

The class ReferenceTrajectory can be passed to or used within the Controller of the SimulationEnvronment. It serves as an abstract base class to define a reference trajectory that the ControlLaw aims to track while computing its control action.
