Observer-Based Non-Fragile Passive Control for Uncertain Nonlinear Sampled-Data System with Time-Delay

The problem of observer-based passive control for uncertain nonlinearsampled-data systems with time delay is investigated by using non-fragile passivecontrol. Attention is focused on the design of a non-fragile passive observer and acontroller which guarantees the passivity of the closed-loop system for all admissibleuncertainties. A sufficient condition for passivity and asymptotic stability of thecombined system is derived via linear matrix inequality (LMI). Finally, a simulationexample is presented to show the validity and advantages of the proposed method
