摘要:

本文研究了受时间触发或空间触发重置影响的线性与仿射混合系统的动力学与控制问题。混合轨迹可能出现连续时间系统中不存在的退化现象,即拍击、阻塞和芝诺行为。这些病态现象通常通过强制事件间时间下界来避免。虽然这一约束对于时间触发重置易于实现,但对于空间触发系统则无法实现。特别地,线性空间触发混合系统总是存在拍击和阻塞轨迹,而仿射系统还可能包含芝诺轨迹。本文在仿射混合系统背景下研究了混合庞特里亚金最大值原理,探讨了诱导协态跳变条件的存在性与唯一性,由此引入了强驱动与弱驱动重置的概念。最后,讨论了拍击和芝诺背景下的最优控制问题,并以数值示例作为结论。

英文摘要:

A study of the dynamics and control for linear and affine hybrid systems subjected to either temporally- or spatially-triggered resets is presented. Hybrid trajectories are capable of degeneracies not found in continuous-time systems namely beating, blocking, and Zeno. These pathologies are commonly avoided by enforcing a lower bound on the time between events. While this constraint is straightforward to implement for temporally-triggered resets, it is impossible to do so for spatially-triggered systems. In particular, linear spatially-triggered hybrid systems always posses trajectories that are beating and blocking while affine systems may also include Zeno trajectories. The hybrid Pontryagin maximum principle is studied in the context of affine hybrid systems. The existence/uniqueness of the induced co-state jump conditions is studied which introduces the notion of strongly and weakly actuated resets. Finally, optimal control in the context of beating and Zeno is discussed. This work concludes with numerical examples.
