Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This component generates a periodic clock that starts ticking when the simulation starts. The period is defined as the product of a resolution, defined with enumeration Resolution, and Integer parameter factor. Internally, the period is represented as a rational number. All clocks with rational number definitions are exactly time synchronized to each other.
Example:
import Modelica.Clocked.ClockSignals.Clocks;
import Modelica.Clocked.Types;
Clocks.PeriodicExactClock periodicClock(factor=10,
resolution=Types.Resolution.ms);
// Clock ticks every 1/100 seconds
For an introduction to clocks see UsersGuide.Clocks.
If a clock is associated to a clocked continuous-time partition, then an integrator has to be defined that is used to integrate the partition from the previous to the current clock tick. This is performed by setting parameter useSolver = true and defining the integration method as String with parameter solver. Both parameters are in tab Advanced. For an example, see Examples.Systems.ControlledMixingUnit.
