Pytorch hyperparameter tuning

Field Oriented Control Following the standard argument, the FOC algorithm is obtained as follows: In the rotor-fixed frame the voltages and currents are nearly static, slowly time-varying quantities. They are thus much easier to control than the fast time-varying signals in the stator-fixed frame, since a lower controller bandwidth is acceptable.
