Event-Triggered Sampled-data Disturbance Attenuation for Uncertain Fuzzy Systems: Positivity and Separation Principle

초록

This paper addresses the positive sampled-data observer-based output-feedback control problem for Takagi-Sugeno fuzzy models with uncertainties. Leveraging an aperiodic sampling framework driven by event-triggering mechanisms, we propose a sampled-data design technique aimed at achieving positive ${\mathcal{L}}_2$-${\mathcal{L}}_{\infty }$ disturbance attenuation. A distinctive fuzzy OBOF controller is separately designed to enhance closed-loop positivity. This study investigates the Zeno-free behavior of the designed controller. A numerical example demonstrates the effectiveness of our proposed methodology.
