Input
The current control unit is comprised of a PI control unit for d-axis and a PI control unit for q-axis, and
ΔID = VEIDREF ×2^16 - ID
VDI = VECIDKI ×2^16 × ΔID ×2+ VDI
VEVD = (VECIDKP ×2^16 × ΔID ×2+ VDI) / 2^32 : Voltage calculation using proportional term
ΔIQ = VEIQREF×2^16 - IQ
VQI = VECIQKI ×2^16 ×ΔIQ ×2+ VQI
VEVQ = (VECIQKP ×2^16 × ΔIQ ×2 + VQI) / 2^32 : Voltage calculation using proportional term
