RelativePositionSensor

Ideal sensor to measure the position of flange_b relative to flange_a

This component extends from PartialRelativeSensor

Usage

RelativePositionSensor()

Connectors

  • flange_a - (Flange)
  • flange_b - (Flange)
  • s_rel - This connector represents a real signal as an output from a component (RealOutput)

Behavior

\[ \begin{align} 0 &= \mathtt{flange\_b.f}\left( t \right) + \mathtt{flange\_a.f}\left( t \right) \\ \mathtt{s\_rel}\left( t \right) &= \mathtt{flange\_b.s}\left( t \right) - \mathtt{flange\_a.s}\left( t \right) \\ 0 &= \mathtt{flange\_a.f}\left( t \right) \end{align} \]
