Speed regulation method for DC and AC electric motors

摘要

The revs regulation method uses superimposed current and torque regulation, with direct correction of the difference between the actual revs (Nist) and the required revs (Nsoll) by a proportional element (2), compensation of the load moment by a load- dependent pre-control signal (a15) and elimination of the rev disparity by an integral element (4). The load rotation rate (nL) and the load torque (mL) are determined for an oscillatory drive train via an inverse model (23).
