As you know there are 5 types of FOC control: 

This means that the special synchronous reference frame should be linked to one of the flux linkages space vectors. However, for vector control schemes there are two more possibilities, related to the currents space vectors: stator and rotor currents:

1-Stator flux field orientation 

2-Rotor flux field orientation (RFO) 

3-Air-gap flux field orientation (AFO) 

4-Stator current orientation (SCO) 

5-Rotor current orientation (RCO)
