Resumen:
A finite-time observer for a class of linear time-varying systems with
bounded unknown inputs is presented in this note. The design of the
observer exploits structural properties of the system and, through a
linear operator, allows applying the robust exact differentiator in a
block form without requiring additional stabilizing terms. The proposed
observer provides an exact estimate of the states after a finite
transient time despite the possible instability of the system and the
effects of bounded unknown inputs.
