How can I know PU(per unit) real value & decoupling vd/vq ?

Hi I'm using 'High Voltage Motor Control and PFC Developer's Kit' - HVMotorCtrl + PfcKit_v2.1 ( HVPM_Sensored_servo )

I have some question.

I want to decoupling control.  ipark1.Qs = pi_iq.out + wr(L*park1.Qs+flux) 

But i think it's not correct. Because ipark1.Qs & pi_iq.out  are Per Unit, but the value of wr(L*park1.Qs+flux)  is not. Only park1.Qs is PU.

1 . How can i use decoupling control in PU & IQmath system? 

2. I want to know real value of  PI_MACRO output. ( This will be Q-axis voltage Vq. )

pi_iq.out * Base_voltage is the real value of Vq? ( DCbus 300V, base_voltage is 300/squr(3) )

Is it right?

plz answer my question!
