TheSpeed-upfunctionisusedinordertoavoidoscillationsinpresenceofloadswithahighmomentofinertia.
Itismadeupofaderivativepartinthespeedfeedbackcircuit,whichallowstoincreasetheintegralgainofthe
speedregulator.Itisalsousefulincaseofcyclicalnonconstantloadsonthemotor(ex.cams).Thefeedback
appliedtothespeedregulatorismadeoftwocomponents:
- themotorspeed
- theoutputsignalfromtheSpeedupfunction
ThisfunctionismutuallyexclusivetotheInertia/loss compfunction,ThisselectionmustbedoneviatheAux
