In the following, the paper focuses on the MWD = 0[degrees]N that produces the worst case of wave disturbance
. A preliminary analysis was carried out with a graphical method called the mirror-imaged diffraction method [1, 16].
Representative examples of wave disturbance
spectra are shown in Figure 2.
[u.sub.c] = [[[u.sub.c1],[u.sub.c2]].sup.T] is the flap command of the hydrofoil transmission system, and [f.sub.2](t) = [d.sub.2](t) - [DELTA][a.sub.2][z.sub.2] is the composite disturbance caused by model uncertainties and external wave disturbance
, and [DELTA][a.sub.2] is the perturbation item of [a.sub.2].
By solving a convex optimization problem and using LMI technique, the estimation performance is enhanced and the wave disturbance
influence is restricted.
Therefore, the fin stabilizer has difficulty in accurately resisting wave disturbance
, which will definitely reduce the antirolling effect.
Direct evidence of phosphorus outbreak release from sediment to overlying water in a large shallow lake caused by strong wind wave disturbance
. Chinese Science Bulletin,, 50(6):577-582, 2005.
They cover diagnostics of plasma perturbations by using Doppler radio sounding, diagnostics of plasma wave disturbance
by incoherent scatter and Doppler radars, diagnostics of geomagnetic disturbances, rocket burn and launch and radio communication, and ecological problems in near-the-earth space activity.
ASV (autonomous surface vehicle) rolls severely if it is navigating near water surface and wave disturbance
has an obvious effect on its motion attitude.
It is operated in the sea condition and is swayed by the wave disturbance
. The frame system has a steady structure to stand total payload of the crane system.
The algal turf retained space and persisted during the entire year without serious damage by abrasion or wave disturbance
. Major fluctuations in its abundance were related to thickness rather than cover and, when disturbed, its rate of recovery was rapid, despite potential differences related to the timing of disturbance.
