Tn q-current controller
Integral action time of the q-current controller,
Units: ms
For description, see
.
47.9
Kp d-current controller 4kHz
Proportional gain of the d-current controller at 4 kHz PWM frequency,
Units: V/A
According to the optimum magnitude and taking account of the internal standardizations,
Kp and Tn for the Id current controller at 4 kHz PWM frequency can be set as follows:
T
n
= L
sd
/ r
s
(ms)
where r
s
= Stator resistance in ohms, cold
k
p
= L
sd
/(3*Tab) = L
sd
/(3*0.125) = 2.667* L
sd
(L
sd
in mH)
For asynchronous motors, the total leakage inductance L
sigma
must be used instead of
L
sd
.
47.10
Tn d-current controller
Integral action time of the d-current controller,
Units: ms
For description, see
.
