基于模糊神经网络控制的水面无人艇建模与仿真 总被引:1,自引:0,他引:1
水面无人艇(USV)的控制是智能控制与船舶控制的一个重要研究方向.由于船舶运动的复杂性,自动航向控制是水面无人艇研究中的一个关键问题,传统控制方法很难取得好的控制效果.本文对模糊逻辑和神经网络智能控制方法及其在船舶航向控制的运用进行了研究.选取滑行艇作为无人艇艇体,采用喷水推进装置,利用模糊神经网络对艇体的航向进行控制,利用Matlab软件对水面无人艇进行建模,对3种海况干扰无人艇的情况进行实时仿真,仿真结果基本令人满意. 相似文献

无人水面艇反潜战载荷分析 总被引:2,自引:0,他引:2
反潜型无人水面艇可以有效提高执行反潜任务的效费比,但无人水面艇反潜战载荷与传统作战平台的反潜任务系统相比有较大区别,无人水面艇反潜战载荷走向实用面临诸多问题。本文从无人水面艇反潜任务需求、反潜战载荷适装性、反潜战载荷集成方式和使用方式等方面对无人水面艇反潜战载荷进行了综合分析,可为反潜型无人水面艇以及无人水面艇反潜战载荷的设计和使用提供借鉴和参考。 相似文献

为了研究滑行艇作为高速拖曳水面搭载平台的可行性,通过模型试验方法对滑行艇在静水和波浪中的阻力性能及航行姿态变化情况开展研究,分别在非拖曳与拖曳2种工况下进行试验。在静水条件下,研究了滑行艇在不同航速时的阻力及航态变化,讨论了拖曳力对航行性能的影响。在规则波条件下,对滑行艇在排水状态和滑行状态,以及不同波长、不同波高的情况下进行模型试验,讨论了拖曳力对阻力平均值、纵摇、垂荡以及首部加速度的影响程度。通过试验结果对比分析,总结了拖曳力对滑行艇阻力及航态的影响规律,并提出了滑行艇作为高速拖曳水面搭载平台时的建议。 相似文献

Site-based projects were initiated in Chawka Bay-Paje, Zanzibar, and Nyali-Bamburi-Shanzu, Kenya, to demonstrate the benefits of an integrated coastal management (ICM) approach for addressing coastal issues such as tourism development and enhancement of resource-dependent village economies in eastern Africa. A two-year, multidonor project used three primary strategies to make rapid, but sustainable, progress toward ICM. These included using interagency government teams for ICM planning, adopting an internationally recognized framework for ICM as a project ''road map,'' and explicitly incorporating capacity-building strategies into all aspects of the project. Within two years, integrated ICM action strategies, prepared through participatory processes, were being implemented at both sites, and both teams were working to expand the scale and scope of ICM in their nation. More importantly, the project helped create committed, capable, interagency groups that continue to work together to address urgent ICM issues. 相似文献
