RampTest

Usage

RampTest()

Behavior

\[ \begin{align} \mathtt{signal.y}\left( t \right) &= \mathtt{integrator.u}\left( t \right) \\ \frac{\mathrm{d} \mathtt{integrator.x}\left( t \right)}{\mathrm{d}t} &= \mathtt{integrator.k} \mathtt{integrator.u}\left( t \right) \\ \mathtt{integrator.y}\left( t \right) &= \mathtt{integrator.x}\left( t \right) \\ \mathtt{signal.y}\left( t \right) &= ifelse\left( \mathtt{signal.start\_time} < t, ifelse\left( t < \mathtt{signal.duration} + \mathtt{signal.start\_time}, \mathtt{signal.offset} + \frac{\mathtt{signal.height} \left( - \mathtt{signal.start\_time} + t \right)}{\mathtt{signal.duration}}, \mathtt{signal.height} + \mathtt{signal.offset} \right), \mathtt{signal.offset} \right) \end{align} \]
