We derive sufficient conditions for the solvability of the state estimation problem for a class of
nonlinear control time-varying systems, which includes the dynamics that have a triangular …

This paper presents results on the solvability of the observer design problem for general
nonlinear triangular systems with inputs, under weak observability assumptions. The local …

For a wide class of triangular nonlinear control systems, sufficient conditions for the
solvability of the observer design problem are established. The state estimation is exhibited …

The paper deals with the observer design problem for a wide class of triangular nonlinear
time-varying systems. The results of the present work generalize previous results in the …
