| 英文摘要 |
| In this paper, a dynamic event-triggered funnel tracking control scheme is proposed for a class of switched
nonlinear systems with arbitrary relative degree and partial non-input-to-state stability inverse dynamics. First of all, a
virtual output is introduced to convert an arbitrary relative degree switched nonlinear system into a switched nonlinear
systems with relative degree one. Second, by designing event-triggered funnel controller of individual subsystem and a
switching dynamic event-triggering mechanism, the problem of asynchronous switching between candidate event-triggered
funnel controllers and subsystems is addressed. The proposed scheme eliminates the conservativeness caused by the design
of a common controller for all subsystems in the existing literature. It is ensured that under a class of switching signals
with average dwell time, all signals in the switched closed-loop system are bounded, and the tracking error evolves within
a prescribed funnel all the time. Also, Zeno phenomenon of sampling is avoided. Finally, one example is utilized to verify
the applicability and effectiveness of the proposed control scheme. |
