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。
