When Direct Torque Control (DTC) is used in variable frequency drives to control the torque of three-phase AC electric motors., you can interpret physically and analytically decoupling between flux and torque at the ?
Dear Zoheir,
May be I am wrong but decoupling has no formal physical interpretation as it is mainly a way to determine a model for control.
Best regards,

Dear Mohmed,
Thanks to your intervention. But decoupling should be done at the level of the machine until the flux and torque are separately controlled.

Dear Zouheir
Yes, the Direct Torque Control (DTC) to separate the control of the stator flux(to control the speed) and the control of the torque by action on the rotor flux.
