In this dissertation, through computer simulation, the problems of modeling, control and guidance of auvs are presented. the first part of this dissertation addresses the problem of dynamically modeling of auvs, and derives thrusters " two - dimension nonlinear dynamic model, which has axial flow speed and propeller rotational velocity as two state variables, voltage or current of motor as inputs, and thruster force and torque as output. the second part focuses on the nonlinear adaptive sliding mode control of auvs in diving plane and steering plane
本論文系統研究了自主式水下航行器的建模、非線性自適應滑模控制、以及深度調整和水平面導引方法等問題，具體成果和創新點如下1 、根據流體力學理論，建立了螺旋槳推進器的動態模型，它以螺旋槳來流速度v _ p和螺旋槳轉速n為狀態變量，以電機施加轉矩為輸入，螺旋槳推力t和轉矩q為輸出。The spiral sheet metal carry the lotus test to be apply in the bearing power test of the deep foundation soil and water table following foundation soil extensively because the ability goes into the surface of earth is following the certain depth area curve carry on test, according to the element that the spiral sheet metal carries the lotus test, through contrast with plate load test, the spiral sheet metal carries the lotus test to be applicable to the shallow storey foundation soil equally, the size of the spiral sheet metal time area concentration diagram is not big to the test result influence, the spiral sheet metal carries the bearing power of the lotus test assurance to no longer carry on the depth area curve redress
摘要螺旋板載荷試驗因能旋入地面以下一定深度進行試驗而廣泛應用於深層地基土及地下水位以下地基土的承載力測試，根據螺旋板載荷試驗的原理，經與平板載荷試驗對比，螺旋板載荷試驗同樣適用於淺層地基土，螺旋板面積的大小對試驗成果影響不大，螺旋板載荷試驗確定的承載力不再進行深度修正。I strongly advise you not to do this trick at all. if you do it, do it over water. this trick is also called death spiral : for a reason ! !
首先：不建議做這個動作；其次如果你要做，那就在水面上作。在50米的高度上進入螺旋，螺旋速度不要太快，只需要你自己的水平位置比內側翼尖稍高，然後接近地面。
