文档介绍：puter interaction module. Meanwhile, and adopts the water valve and valve con trol at the same time. Compared with the conventional control mode, it is more effecti ve in controlling the output control feedback, so the water tank has a better anti swa
y effect in the practical application.
Finally, the paper gives results after experimental bench test of the anti-rolling ta nk. The results show that the water tank and control theory has certain damping effec
t on the simulation of the wave, and this paper has the vital significance for the stud y on damping control theory and design of experimental bench.
