Abstract

In this article, by coupling sliding-mode differentiators with a tool capable of inverting, in finite time, the suspension of the observability map, a local finite-time observer for nonlinear control systems is proposed. Differently from other approaches, this observer does not rely on a change of coordinates and provides the state estimates in the original coordinates.
