 Flux-Vector Control
 ===================
 
-Flux vector control directly controls the stator flux magnitude and the electromagnetic torque, which simplifies reference generation especially in the field-weakening region [#Pel2009]_. We use the control law that results from feedback linearization of the flux and torque dynamics [#Awa2019]_. Here, the inclusion of integral action is briefly discussed, as an extension to [#Tii2025a]_. Furthermore, these notes aim to provide a link between the column-vector and complex-vector formulations of the control law. Here, a synchronous machine is considered as an example (see the :ref:`synchronous-machine` document for the model and notation), but the approach is analogous for induction machines.
