Relative Threshold-Based Event-Triggered Control for Nonlinear Constrained Systems With Application to Aircraft Wing Rock Motion

This article concentrates on the event-driven controller design problem for a class of nonlinear single input output parametric systems with full state constraints. A varying threshold triggering mechanism is exploited, which makes communication more flexible. Moreover, from viewpoint energy conservation and consumption reduction, system capability becomes better owing to contribution proposed event-triggered mechanism. In meantime, developed control strategy can avoid Zeno behavior since lower bound sample time provided. The considered plant in triangular form, match condition not satisfied. To ensure that all states retain predefined region, barrier Lyapunov function (BLF) based adaptive law developed. Due existence uncertainties, an algorithm presented as estimated tool. All signals appearing closed-loop are then proven be bounded. Meanwhile, track given signal far possible. end, effectiveness approach validated by aircraft wing rock motion system.
