V/Hz Control
------------

These examples demonstrate observer-based V/Hz (O-V/Hz) control for synchronous machines [#Tii2025aa]_ and induction machines [#Tii2025bb]_. The example :doc:`/drive_examples/vhz/plot_2kw_ipmsm_2mass_ovhz` demonstrates the use of a two-mass mechanics model. Furthermore, the examples :doc:`/drive_examples/vhz/plot_2kw_im_diode_vhz` and :doc:`/drive_examples/vhz/plot_2kw_im_lc_vhz` show operation of an induction machine under pure open-loop V/Hz control with a diode front-end rectifier and with an LC filter, respectively.
