1-14 Damping Gain
Range:
Function:
of the PM machine. High damping gain
will give high dynamic performance and
low damping gain will give low dynamic
performance. The dynamic performance is
related to the machine data and load type.
If the damping gain is too high or low the
control will become unstable.

[0.01 - 20 s] High pass-filter damping time
constant determines the response
time to load steps. Obtain quick
control through a short damping
time constant. However, if this value
is too short, the control gets
unstable. This time constant is used
below 10% rated speed.

Machine Supply Voltage Filter
Time constant is used for reducing
the influence of high frequency
ripples and system resonances in
the calculation of machine supply
voltage. Without this filter, the
ripples in the currents can distort
the calculated voltage and affects
the stability of the system.
