This research supports the nation's defense and space programs by providing new methods for controlling aerial and space vehicles, e.g., drones, missiles, rockets, landers, and ascent vehicles. The research also promotes the progress of science by addressing an unresolved issue: aerial and space vehicles have actuators (propellers, control surfaces, thrusters) that can only produce a limited amount of force when maintaining the vehicle's flight path. For example, Martian landers and ascent vehicles are sensitive to unpredictable environmental forces that may prevent them from following their desired trajectory. To counterbalance these forces, the flight control system may have to request thrust commands that exceed the limits of the vehicle's thrusters. The consequence: undesirable flight performance which may hinder the mission. To avoid this, control engineers presently exploit over-sized thrusters at the expense of increased vehicle weight and cost. This research provides control methods that safeguard against this consequence allowing control engineers to design vehicles with smaller sized actuators, hence providing vehicle weight, cost, and scheduling savings. Integrated research, teaching and outreach activities will be carried out through affiliations with university institutes and external centers that foster multidisciplinary collaboration among engineering and other STEM departments, and through collaborations with scholarly organizations that serve historically underrepresented populations. The project will have an impact at the international level through this joint United States/United Kingdom collaboration.

这项研究通过提供控制航空和太空车辆的新方法来支持美国的防御和太空计划，例如无人机，导弹，火箭，登陆器和上升车辆。该研究还通过解决尚未解决的问题来促进科学的进步：空中和太空车辆具有执行器（螺旋桨，控制表面，推进器），这些执行器在维持车辆的飞行路径时只能产生有限的力。例如，火星着陆器和上升车辆对不可预测的环境力量敏感，这些力量可能阻止它们遵循所需的轨迹。为了平衡这些力量，飞行控制系统可能必须要求超过车辆推进器限制的推力命令。结果：不良的飞行性能可能会阻碍任务。为了避免这种情况，控制工程师目前会以增加车辆的重量和成本为代价来利用超大的推进器。这项研究提供了控制方法，可以保护这种后果，从而使控制工程师可以设计具有较小尺寸的执行器的车辆，从而提供车辆的重量，成本和计划节省。综合研究，教学和外展活动将通过与大学机构和外部中心的隶属关系进行，从而促进工程和其他STEM部门之间的多学科合作，并通过与为历史上代表性不足的人群提供服务的学术组织的合作。该项目将通过这一联合美国/英国合作在国际层面产生影响。
