摘要：
本文研究了异步切换下切换系统的有限时间控制和无扰切换控制。首先，设计了一类动态输出反馈控制器，以在系统输出可测时稳定切换系统。考虑到瞬态性能的改善，在控制器设计中进一步研究了无扰切换控制和有限时间控制。为避免控制跳变，引入了一个实用滤波器使控制信号更平滑且连续。此外，为在短时间间隔内获得有限时间有界的系统状态，在利用平均驻留时间管理切换过程时考虑了有限时间分析。提出了分析闭环系统有限时间稳定性和有限时间有界性的新准则，并新提出了优化控制器增益的可解条件。最后，通过在boost converter中的应用验证了所提方法的优越性。
英文摘要：
In this paper, the finite-time control and bumpless transfer control are investigated for switched systems under asynchronously switching. First, a class of dynamic output feedback controllers are designed to stabilize the switched system with measurable system outputs. Considering the improvement of transient performance, the bumpless transfer control and finite-time control are further studied in the controller design. To avoid the control bumps, a practical filter is introduced to make the control signal smoother and continuous. Furthermore, to derive a finite-time bounded system state over short-time intervals, the finite-time analysis is considered in managing the switching process with the average dwell time. New criteria are proposed to analyze the finite-time stability and finite-time boundedness for the closed-loop system and solvable conditions are newly proposed to optimize the controller gain. Finally, the superiorities of the proposed method are validated through an application to a boost converter.
