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.
摘要翻译： 光纤陀螺可以克服常规光纤陀螺相位调制方法，带有锯齿波调制和数字调制的闭环系统所遇到的缺陷。 在干涉光强度信号I中通过使用三角波形即三角波形波形信号产生参考相位差DELTAβ和斜坡相位差σ。 参考相位差DELTA beta被改变为恒定值DELTA beta A和DELTA beta B，其绝对值相同，每个符号TA和TB的符号不同。 干涉光强度信号I的相位x变为等于x =DELTAθ+ sigma +ΔTATA。 控制斜坡相位差σ以满足DELTAθ+ sigma = 0。 因此，在控制回路的稳定点，Sagnac相位差ΔTATA等于斜坡相位差σ。 此外，干涉光强度信号I的相位x不包含Sagnac相位差DELTAθ，因此x =ΔTATA。 此外，光纤陀螺仪可以消除偏压，特别是光学产生的偏压。 在相位调制方法或三角速度系统的光纤陀螺仪中，相位控制器被提供有周期T的相位控制电压信号VS和周期T的方波信号V2，用于校正由产生的幅度调制引起的光偏置 通过相位控制电压信号VS以相加的形式。 方波信号V2具有恒定的幅度H，并且在相位控制电压信号VS最大化或最小化的点处极性反转。 选择幅度H和方波信号V2的极性使得光偏置最小化。

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.
