中文简介: | 混合系统是一种建模工具,允许连续和离散状态动力学的组合。它们可以表示为连续系统,运行模式由离散动力学建模,两种动力学相互影响。混合系统在建模一系列重要问题时至关重要,例如飞机飞行管理、空中和地面运输系统、机器人车辆和人类自动化系统。这些系统在控制中使用离散逻辑,因为离散抽象使其更容易管理复杂性,离散表示更自然地适应控制器设计中的语言和定性信息。近年来,大量的研究集中在混合系统控制器的综合上。对于混合系统的安全规范,即设计控制器使系统远离不安全状态,我们将提出一种基于最优控制和博弈论的综合和计算技术。我们将简要回顾这些方法及其在空中交通管理系统、有人和无人机网络中的防撞和航空电子设备设计中的应用。然后,我们将提供一个将可达性与机器学习技术相结合的方法工具箱,以便在保持安全的同时提高性能。我们将在伯克利的四旋翼无人机实验平台上演示这些“安全学习”方法。 |
课程简介: | Hybrid systems are a modeling tool allowing for the composition of continuous and discrete state dynamics. They can be represented as continuous systems with modes of operation modeled by discrete dynamics, with the two kinds of dynamics influencing each other. Hybrid systems have been essential in modeling a variety of important problems, such as aircraft flight management, air and ground transportation systems, robotic vehicles and human-automation systems. These systems use discrete logic in control because discrete abstractions make it easier to manage complexity and discrete representations more naturally accommodate linguistic and qualitative information in controller design. A great deal of research in recent years has focused on the synthesis of controllers for hybrid systems. For safety specifications on the hybrid system, namely to design a controller that steers the system away from unsafe states, we will present a synthesis and computational technique based on optimal control and game theory. We will briefly review these methods and their application to collision avoidance and avionics design in air traffic management systems, and networks of manned and unmanned aerial vehicles. Then, we will present a toolbox of methods combining reachability with machine learning techniques, to enable performance improvement while maintaining safety. We will illustrate these “safe learning” methods on a quadrotor UAV experimental platform which we have at Berkeley. |
