ABSTRACT:
A rate-control servomechanism includes a load driving motor and a tachometer mounted on the motor shaft to produce a feedback signal hich corresponds to the rotational speed of the motor. An additional signal corresponding to the motor current is added to the tachometer feedback signal to compensate for the resonance-like effects resulting from the inductive coupling between the motor and tachometer windings.
