Stability tuning can be tailored for optimum performance when operating in field current regulation mode.
BESTCOMSPlus FCR stability settings are illustrated in Figure 14-4.
FCR Mode Stability Settings
The DECS-150 bases its field current output upon the following settings.
The proportional gain (K
p
) is multiplied by the error between the field current setpoint and the actual field
current value. Decreasing K
p
reduces overshoot in the transient response. Increasing K
p
speeds the
transient response.
The integral gain (K
i
) is multiplied by the integral of the error between the current setpoint and the actual
field current value. Increasing Ki reduces the time to reach a steady state.
The derivative gain (K
d
) is multiplied by the derivative of the error between the current setpoint and the
actual field current value. Increasing K
d
reduces ringing in the transient response.
Additional FCR stability settings remove the noise effect on numerical differentiation (derivative time
constant T
d
) and set the voltage regulator gain level of the PID algorithm (K
a
) with recommended gain
calculation.
