“…The waves are extremely irregular: wave height, wavelength and period are random variation, which make the ship rocking irregularly and pose a real challenge for the dynamic performance of FOG. Ship rocking movement is complex: variable angular velocity motion and variable angular acceleration motion, which can be regarded as the superposition of simple harmonic motion of ocean wave with different frequencies and amplitudes [1,2]. Generally, in order to facilitate the discussion, this motion has been simplified: it can be simulated with the simple harmonic motion (i.e.…”

The sway motion of ships follows sine law. Therefore, it needs high dynamic performance of fiber optic gyroscope (FOG) to meet the serious working environment. A new test method was introduced to make reasonable assessment on the dynamic performance of FOG. The principle of this new test method was that the sine wave provided by the IP core in FPGA was superimposed on the digital ladder to simulate the input signal of sway motion. It could be proved that the serial of sine signal, which was generated by this method, was equivalent to the external input signal. Moreover, the dynamic error model of FOG was established to provide the theory of dynamic test. The results of dynamic test of FOG indicated that the dynamic error did not have divergent trends, the system parameters set was reasonable and the FOG system was stable. It also can be seen that dynamic error of FOG was increased with the increasing of sine wave amplitude, which was accord with the actual situation. The new dynamic test method of FOG was verified.
