I have a a Field Oriented Control with the PI control for Speed and Current implemented for BLDC motor. After the Inv. Park transform, Carthesian to Polar tranform is used and then Space Vector Modulation performed. I am not able to understand how the limitation of the max space vector value is taken into account, which factors decide its maximum value and how its related. Is there any way i can confirm that operation of the system is within the space vector hexagon.

Thanks,
Adnan
