摘要： A fiber optic gyro can overcome the defects encountered with conventional fiber optic gyros of phase-modulation method, closed-loop system with serrodyne modulation and digital modulation. A reference phase difference .DELTA..beta. and a ramp phase difference .sigma. are generated in an interference light intensity signal I by use of a triangular waveform, i.e., delta serrodyne waveform signal. The reference phase difference .DELTA..beta. is changed to constant values .DELTA..beta..sub.A and .DELTA..beta..sub.B whose absolute values are the same and whose signs are different at every times T.sub.A and T.sub.B. A phase x of the interference light intensity signal I becomes equal to x=.DELTA..theta.+.sigma.+.DELTA..beta.. The ramp phase difference .sigma. is controlled so as to satisfy .DELTA..theta.+.sigma.=0. Accordingly, at the stable point of the control loop, a Sagnac phase difference .DELTA..theta. is equal to the ramp phase difference .sigma.. Further, a phase x of the interference light intensity signal I does not contain the Sagnac phase difference .DELTA..theta., and hence x=.DELTA..beta.. Also, a fiber optic gyro can eliminate a bias, in particular, optically-generated bias. In a fiber optic gyro of phase-modulation method or delta serrodyne system, a phase controller is supplied with a phase control voltage signal V.sub.S of period T and a square wave signal V.sub.2 of period T for correcting an optical bias caused by an amplitude modulation generated by the phase control voltage signal V.sub.S in the added form. The square wave signal V.sub.2 has a constant magnitude H and is inverted in polarity at points in which the phase control voltage signal V.sub.S is maximized or minimized. The magnitude H and the polarity of the square wave signal V.sub.2 are selected such that an optical bias is minimized.

摘要： The present invention relates to an automatic steering apparatus for ships which prevents the occurrence of directional instability due to unusual phenomena which occur at small rudder angles of so-called full-bodied ships.When the rudder angle of such ship is small, two stable steady turning conditions occur so that the turning movement cannot assume any single state and it results in a frequent and irregular unstable ship motion. Thus, in accordance with the invention there is provided an automatic steering apparatus of the type in which a command rudder angle signal is produced from a deviation signal representing the difference between a predetermined course and the ship's heading by means of a operational circuit and a rudder angle servomechanism, wherein a compensating circuit is provided before the operational circuit and the gain of the compensating circuit is increased when the deviation signal is in the small range, thus preventing any unstable ship motion of the ship and thereby preventing the occurrence of directional instability.
