Abstract:

Two techniques, both of which use the Faraday bias effect, were investigated for eliminating or reducing the lock-in effect. One technique, dual FM bias, is a passive scheme which uses two ac bias signals which drive the RLG through the lock-in region in such a manner that lock-in does not occur. Dual FM bias is discussed in Volume I. The second bias technique, servo-linearization, uses an active control technique for effectively canceling the internal forcing signals causing lock-in. Servo-linearization, an Autonetics proprietary technique, is the subject of this section. The basic principles of the servo-linearization technique are presented first. Included in this discussion is an enumeration of some of the advantages and disadvantages of the technique. The results obtained from a computer analysis of the servo-linearization technique are given next. The discussion concludes with a presentation of the experimental servo-linearization hardware designed, constructed, and tested.
