The synchronous Modelica language elements allow for the first
time to utilize a continuous-time, nonlinear, inverse model in
a Modelica sampled-data system, by automatically discretizing
this model and providing it as a clocked partition. This allows
a convenient definition of certain nonlinear control systems,
see example
Examples.Systems.ControlledMixingUnit.
Several practical details to use nonlinear inverse plant models in
a control system are discussed in the following reference:

The synchronous Modelica language elements used in this library
are based on the clock calculus and inference system proposed by [Colaco2003]
and implemented in Lucid Synchrone version 2 and 3 [Pouzet2006].
However, the Modelica approach also uses multi-rate periodic clocks based on
rational arithmetic introduced by [Forget2008], as an extension of
the Lucid Synchrone semantics. These approaches belong to the class of
synchronous languages [Benveniste2003]:
