Global Adaptive Regulation of a System under Unknown Saturated Input: An Event-Triggered Gain-Scaling Factor Method
Abstract
In this letter, we address a global adaptive regulation problem for a class of systems subject to unknown input saturation. A notable feature is that the saturation bounds are unknown and time-varying. To handle this unknown input saturation, we propose a novel event-triggered gain-scaling state-feedback controller. It is analytically shown that the resulting closed-loop system achieves global regulation and that Zeno behavior is excluded. An illustrative example with comparative results is provided to demonstrate the effectiveness and validity of the proposed approach.
