摘要:

研究了一类线性时变切换系统的实时模式调度问题。混合控制算法的执行时间对于实时应用来说通常是令人望而却步的,并且通常只能以近似精度为代价来减少。我们解决这个权衡利用系统的线性度,制定一个基于投影的方法,使开环优化过程中不需要模拟。一个数值例子显示了如何建议的开环算法优于采用普通的数值积分技术的方法。此外,我们遵循滚动时域计划应用实时闭环混合控制的定制实验设置,使用机器人操作系统(ROS)。特别是,我们证明-无论是在蒙特卡洛模拟和实验-最优混合控制有效地调节车和悬挂质量系统的实时性。

英文摘要:

This paper considers the problem of real-time mode scheduling in linear time-varying switched systems subject to a quadratic cost functional. The execution time of hybrid control algorithms is often prohibitive for real-time applications and typically may only be reduced at the expense of approximation accuracy. We address this trade-off by taking advantage of system linearity to formulate a projection-based approach so that no simulation is required during open-loop optimization. A numerical example shows how the proposed open-loop algorithm outperforms methods employing common numerical integration techniques. Additionally, we follow a receding-horizon scheme to apply real-time closed-loop hybrid control to a customized experimental setup, using the Robot Operating System (ROS). In particular, we demonstrate---both in Monte-Carlo simulation and in experiment---that optimal hybrid control efficiently regulates a cart and suspended mass system in real time.
