... water density and the dynamic system of the AUV body may change, resulting in the change of the buoyancy of the AUV and the imbalance of the buoyancy. When the AUV is affected by the residual buoyancy during underwater navigation, (Tangirala, 2007) it will cause the AUV to have a certain pitch angle...

... platform MiniFloat, and used the time domain analysis to study the motion response of the platform under different working conditions. The result showed that the average pitch angle was less than 5° and the amplitude was less than ±15°, indicating that the platform has good motion performance. Ishihara, et...
