Observability of linear systems with commensurate delays and unknown inputs

Then, observers with linearizable error dynamics (see e.g. Few works deal with the design of unknown input observers for nonlinear systems. Some of them are concerned with

Based on the algebraic framework proposed in [19], the problem of causal and non-causal observability of the states and unknown inputs for nonlinear time-delay systems has been

Then this method was applied to study observability of nonlinear time-delay systems with known inputs in [44], to analyze identifiability of parameter for nonlinear time-delay

Considering that the continuous state is known, an algorithm for the discrete state reconstruction in nonlinear uncertain switched systems is presented in [4] based on

In this paper a general class of linear systems with time-delays is considered, which includes linear classical systems, linear systems with commensurate delays, neutral systems

This paper deals with the observability problem of a sort of singular systems with commensurate time-delays in the trajectories of the system, in the time derivative of the
