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.
