The simplified block diagram below illustrates the process PID control.
Note:
When PID is enabled, the PID output generated by the PID set 1 (
) is
used as a reference limiter for speed/frequency reference generated from
MPPT algorithm.
Tracking
In tracking mode, the PID block output is set directly to the value of parameter
. The internal I term of the PID controller is set so
that no transient is allowed to pass on to the output, so when the tracking
mode is left, normal process control operation can be resumed without a
significant bump.
