MultiSensor

Ideal sensor that measures the absolute velocity, the force transmitted from flange_a to flange_b and the power flowing from flange_a to flange_b.

This component extends from PartialRelativeSensor

Usage

MultiSensor()

Connectors

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

Behavior

\[ \begin{align} 0 &= \mathtt{flange\_b.f}\left( t \right) + \mathtt{flange\_a.f}\left( t \right) \\ \mathtt{flange\_a.s}\left( t \right) &= \mathtt{flange\_b.s}\left( t \right) \\ f\left( t \right) &= \mathtt{flange\_a.f}\left( t \right) \\ v\left( t \right) &= \frac{\mathrm{d} \mathtt{flange\_a.s}\left( t \right)}{\mathrm{d}t} \\ \mathtt{power}\left( t \right) &= v\left( t \right) f\left( t \right) \end{align} \]
