Dynamic Event‐Triggered Switching Linear Parameter‐Varying Control for Morphing Aircraft

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This paper investigates a dynamic event‐triggered switching control approach for linear parameter‐varying systems represented in polytopic form. The proposed method ensures asymptotic stability under switching signals, excludes Zeno behaviour, and is validated through simulations of a morphing aircraft model.
