ABSTRACT:
Alternating current provided at an angular frequency (.omega.) for powering an electromagnet force actuator having a leakage inductance (L.sub.1) whereby the alternating current is controlled by a voltage reference and a feedback signal indicative of the controlled current and amplified at a gain factor (K.sub.1) having a magnitude greater than or equal to the leakage inductance (L.sub.1) times the angular frequency (.omega.), whereby the electromagnet has a flat or positive spring rate.
