TorqueSource

Input signal acting as external torque on a spline

This component extends from PartialTorque

Usage

TorqueSource()

Connectors

• spline - (Spline)
• support - (Spline)
• tau - This connector represents a real signal as an input to a component (RealInput)

Variables

Behavior

\[ \begin{align} \mathtt{support.phi}\left( t \right) &= \mathtt{phi\_support}\left( t \right) \\ \mathtt{support.tau}\left( t \right) &= - \mathtt{spline.tau}\left( t \right) \\ \mathtt{phi}\left( t \right) &= \mathtt{spline.phi}\left( t \right) - \mathtt{phi\_support}\left( t \right) \\ \mathtt{spline.tau}\left( t \right) &= - \mathtt{tau}\left( t \right) \end{align} \]
