AccelerationSource

Forced movement of a spline according to an acceleration signal

This component extends from PartialElementaryOneSplineAndSupport

Usage

AccelerationSource()

Connectors

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

Variables

Behavior

\[ \begin{align} \mathtt{support.phi}\left( t \right) &= \mathtt{phi\_support}\left( t \right) \\ \mathtt{support.tau}\left( t \right) &= - \mathtt{spline.tau}\left( t \right) \\ \mathtt{phi}\left( t \right) &= \mathtt{spline.phi}\left( t \right) - \mathtt{phi\_support}\left( t \right) \\ w\left( t \right) &= \frac{\mathrm{d} \mathtt{phi}\left( t \right)}{\mathrm{d}t} \\ a\left( t \right) &= \frac{\mathrm{d} w\left( t \right)}{\mathrm{d}t} \\ a\left( t \right) &= \mathtt{a\_ref}\left( t \right) \end{align} \]
