This research develops a new multi model state estimation method for navigation of Micro Aerial Vehicles (MAVs). MAVs are versatile flying platforms which are increasingly finding applications in industrial inspection, military surveillance and recreational domains. Their primary commercial applications are in the area of outdoor surveying and aerial videography. These applications almost exclusively employ GPS waypoint navigation technology and offline photogrammetry software, to autonomously generate accurate 3D maps and high resolution footage. GPS constrained inspection using MAVs is currently performed manually by radio control and often as single platform implementations. There is a growing need for developing systems and technology which can autonomously perform these routing inspection tasks while exploiting the operational efficiency of multiple MAV platforms. In this scenario an operator can specify an area of inspection of a structure, which is then surveyed autonomously by multiple MAV units while providing sensor telemetry feedback to the user. The capability relaxes the need of expert qualified pilots and waives the need of manual motion control of each platform. ***Multi model estimation strategy is used in applications where multiple models are needed to fully predict the behavior of a system during its operating conditions. MAV systems operate in a range of scenarios with changing sensor availability and environmental disturbances. In order to achieve accurate state estimation during these changing conditions the proposed research will develop a novel multi model estimator design for MAV navigation. The estimator will be designed while focusing on two new sources of information for the navigation system. These include the dynamic model of the platform which models the aerodynamic interactions of the device, and the relative sensing capability of MAVs which exploits the availability of multiple vehicles in a given task. The study will examine new design strategies to achieve computational efficiency, robust performance, system stability, and relative sensing methods that achieve accurate coordination between platforms. The multi model navigation system has many GPS limited industrial applications where automated surveillance and mapping are required. These include ship structure inspection, oil platform underdeck and flare inspection, and disaster surveillance. Moreover, the expected theoretical developments of the proposed research would serve a broader scientific and industrial user base, which includes underwater navigation, intelligent transport systems and flight avionics. It is expected that this research will result in a number of publications with significant impact and training of 2 PhD and 3 Master's students as part of the program.

提出了一种新的多模型状态估计方法用于微型飞行器的导航。微型飞行器是一种多用途的飞行平台，在工业检测、军事监视和娱乐领域得到越来越多的应用。它们的主要商业应用是在户外测量和空中摄像领域。这些应用程序几乎完全采用GPS航点导航技术和离线摄影测量软件，自动生成精确的3D地图和高分辨率镜头。使用MAV的GPS约束检查目前通过无线电控制手动执行，并且通常作为单个平台实现。越来越需要开发能够自主执行这些路由检查任务同时利用多个MAV平台的操作效率的系统和技术。 在这种情况下，操作员可以指定结构的检查区域，然后由多个MAV单元自主地进行调查，同时向用户提供传感器遥测反馈。这种能力放松了对专业合格飞行员的需求，并放弃了对每个平台手动运动控制的需求。* 多模型估计策略用于需要多个模型来完全预测系统在其操作条件下的行为的应用。MAV系统在传感器可用性和环境干扰不断变化的情况下运行。为了在这些变化的条件下实现精确的状态估计，所提出的研究将开发一种新的多模型估计器设计的微型飞行器导航。估计器的设计将集中在两个新的信息来源的导航系统。其中包括平台的动态模型，该模型模拟了装置的空气动力学相互作用，以及MAV的相对传感能力，该能力利用了多个飞行器在给定任务中的可用性。该研究将研究新的设计策略，以实现计算效率，鲁棒性能，系统稳定性，以及实现平台之间精确协调的相关传感方法。多模型导航系统具有许多GPS受限的工业应用，其中需要自动监视和绘图。这些检查包括船舶结构检查、石油平台甲板下和火炬检查以及灾害监测。此外，拟议研究的预期理论发展将服务于更广泛的科学和工业用户群，其中包括水下导航，智能运输系统和飞行航空电子设备。预计这项研究将产生一些具有重大影响的出版物，并作为该计划的一部分培训2名博士生和3名硕士生。
