ThreshStage3On
Parameter ThreshStage…On stipulates the switch threshold for stage2 and
stage3. The switch threshold influences the switching of the stages.
If the actual value drops below Sd_Stage1On the W-FM forms the integral from
control deviationxtime. When the value reaches ThreshStage2On (Q2)
stage2 switches.
If the value reaches ThreshStage3On (Q3) before Sd_Stage1On is not
achieved, stage3 switches.
