Abstract :
This paper investigates the left invertibility for nonlinear time delay system with internal dynamics. Under the assumption imposed on the internal dynamics, it has been shown that the unknown inputs can be estimated. Causal and non causal estimation of the unknown inputs are respectively discussed, and the high-order sliding mode observer is used to estimate the observable states.
