Examples.TestPeriodicClock

Test component that validates the PeriodicClock component.

This component specifically tests the "provoker" / output formulation of the periodic clock. If it works correctly, this component should instantiate and run without error, sampling once per dt seconds.

Usage

DiscreteComponents.Examples.TestPeriodicClock()

Parameters:

Behavior

\[ \begin{equation} \left[ \begin{array}{c} \mathrm{connect}\left( sine_{+}y(t), samplevalue_{+}u(t) \right) \\ \mathrm{connect}\left( samplevalue_{+}y(t), periodicclockprovoker_{+}y(t) \right) \\ \mathtt{sine.y}\left( t \right) = \mathtt{sine.offset} + \mathtt{sine.amplitude} ifelse\left( t \geq \mathtt{sine.start\_time}, \sin\left( \mathtt{sine.phase} + 6.2832 \mathtt{sine.frequency} \left( - \mathtt{sine.start\_time} + t \right) \right), \sin\left( \mathtt{sine.phase} \right) \right) \\ \mathtt{samplevalue.y}\left( t \right) = Sample(ModelingToolkit.InferredClock.var"typeof(InferredClock)"(ModelingToolkit.InferredClock.var"##Storage#InferredDiscrete"(0)))\left( \mathtt{samplevalue.u}\left( t \right) \right) \\ \frac{\mathrm{d} \mathtt{periodicclockprovoker.dummy.dummy}\left( t \right)}{\mathrm{d}t} = 0 \\ \end{array} \right] \end{equation} \]
