An Algebraic Observer for State-Affine Systems
Romeo Ortega, Alexey Bobtsov, Anton Pyrkin +1
We present a new systematic method to design an algebraic swapping lemma observer for nonlinear systems which are affine in the state. Four are the main features of the new observe…

An Algebraic State Observer for a Class of Physical Systems
Alexey Bobtsov, Jose Guadalupe Romero, Romeo Ortega +1
In this paper we present a radically new approach to design state observers for nonlinear systems, with particular emphasis on physical ones. Our objective is to obtain an algebrai…
