A state observer is proposed for a class of uniformly observable systems involving bounded
disturbances. The system outputs are delayed with a known (time-varying) delay and their …

The design of observers for nonlinear systems with unknown, time-varying, bounded delays,
on both state and input, still constitutes an open problem. In this technical note, we show …

This paper proposes a state observer with a cascade structure for a class of nonlinear
