帶拖曳線列陣水面無人艇的避障方法研究
摘要
針對帶有拖曳線列陣的水面無人艇避障問題,提出了基于速度障礙法的無人艇避障方法.對帶拖曳線列陣無人艇進行建模,分析了帶有拖曳線列陣的水面無人艇避障問題,通過設計改進人工勢場法和速度障礙法,實現帶有拖線陣的水面無人艇整體有效避障.仿真結果表明:速度障礙法能降低無人艇避障時拖線陣的有效張力峰值,保持良好的陣形形態,更好地保障陣列的時空安全.

Velocity obstacle collision avoidance approach for USV with towed array
Abstract
For the collision avoidance of unmanned surface vessel (USV) with towed array,an obstacle avoidance method for unmanned boats was presented based on velocity obstacle method.Firstly,the joint model of USV with towed array was established,and the collision avoidance problems for USV with towed array were analyzed.The modified artificial potential field and velocity obstacle methods were designed,to make the joint vessel and array avoid collision.Simulations show that velocity obstacle approach can reduce the effective tensions of array,keep excellent array shapes,implements better array safety in both space and time domains.
