项目摘要
The objective of this work is to generate new fundamental science that enables the operation of cyber-physical systems through complex environments. Predicting how a system will behave in the future requires more computing power if that system is complex. Navigating through environments with many obstacles could require significant computing time, which may delay the issue of decisions that have to be made by the on-board algorithms. Fortunately, systems do not always need the most accurate model to predict their behavior. This project develops new theory for deciding between the best model to use when making a decision in real time. The approach involves switching between different predictive models of the system, depending on the computational burden of the associated controller, and the accuracy that the predictive model provides. These tools will pave the way for more kinds of aircraft to navigate closely and safely with one another through the National Air Space (NAS), including Unmanned Air Systems (UAS). 

The results from this project will enable more accurate and faster trajectory synthesis for controllers with nonlinear plants, or nonlinear constraints that encode obstacles. The approach utilizes hybrid control to switch between models whose accuracy is normalized by their computational burden of predictive control methods. This synergistic approach enables computationally-aware cyber-physical systems (CPSs), in which model accuracy can be jointly considered with computational requirements. The project advances the knowledge on modeling, analysis, and design of CPSs that utilize predictive methods for trajectory synthesis under constraints in real-time cyber-physical systems. 
The results will include methods for the design of algorithms that adapt to the computational limitations of autonomous and semi-autonomous systems while satisfying stringent timing and safety requirements. With these methods come new tools to account for computational capabilities in real-time, and new hybrid feedback algorithms and prediction schemes that exploit computational capabilities to arrive at more accurate predictions within the time constraints. The algorithms will be modeled in terms of hybrid dynamical systems, to guarantee dynamical properties of interest. The problem space will draw from models of UAS in the NAS.
这项工作的目标是产生新的基础科学,使网络物理系统能够在复杂的环境中运行。如果系统很复杂,预测系统未来的行为需要更多的计算能力。在具有许多障碍的环境中导航可能需要大量的计算时间,这可能会推迟必须由机载算法做出的决策。幸运的是,系统并不总是需要最准确的模型来预测其行为。这个项目开发了新的理论,用于在实时做出决策时在最佳模型之间进行决策。该方法包括根据相关控制器的计算负担和预测模型提供的精度,在系统的不同预测模型之间进行切换。这些工具将为更多类型的飞机通过包括无人驾驶航空系统(UAS)在内的国家空域(NAS)进行近距离和安全的相互导航铺平道路。&;#8232;&;#8232;这个项目的结果将使具有非线性对象或编码障碍物的非线性约束的控制器能够更准确、更快地进行轨迹合成。该方法利用混合控制在模型之间切换,模型的精度通过预测控制方法的计算负担来归一化。这种协同方法使计算感知的网络物理系统(CPSS)成为可能,在CPSS中,模型精度可以与计算要求一起考虑。该项目推进了CPSS的建模、分析和设计方面的知识,该系统利用预测方法在实时网络物理系统中进行约束下的轨迹合成。结果将包括设计算法的方法,以适应自主和半自主系统的计算限制,同时满足严格的定时和安全要求。随着这些方法的出现,出现了新的工具来说明实时计算能力,以及新的混合反馈算法和预测方案,它们利用计算能力在时间限制内获得更准确的预测。算法将以混合动态系统的形式建模,以确保感兴趣的动态特性。问题空间将从NAS中的UAS模型中提取。
