Native simulation
=================

These examples simulate systems built in *motulator* natively, i.e., in C, with
:class:`motulator_export.native.Simulation`. The systems are built as in the examples
of *motulator*, and only the simulation object is replaced; the results are those of
*motulator* and can be plotted with its plotting functions. The control system runs
the C port of the control algorithms of *motulator*, which is also used by the PLECS
and Simulink models of this package.

The system is that of the motulator example motulator:drive_examples/flux_vector/plot_6kw_pmsyrm_gn_fvc_fem_harm: the machine model uses a GradNet current map with spatial harmonics, and the control system uses a GradNet flux map, both trained on FEM data. The GradNets are evaluated in C, which makes the native simulation about 30 times faster than motulator.">
