Abstract :
The problem of adaptive fault estimation of linear continuous system with time-varying delay is studied by designing state observer in this paper. By constructing new Lyapunov function and using method of linear matrix inequality (LMI), the new delay-dependent criterion of adaptive fault estimation is proposed. Finally, a numerical example is given to demonstrate the effect of the proposed method.
