**3. Control System**

The main stator winding set of the DOL DWIM is directly connected to the grid and it is tasked with handling the main power flow toward the mechanical load. Differently, the additional stator winding set is supplied by a floating power inverter, which enables a current vector control according to Figure 3. Low-cost devices are used to measure the AC quantities in both windings. An analysis of the different blocks composing the control system is presented in the following.
