Generalized parameter estimation-based observers: Application to power systems and chemical–biological reactors

R Ortega, A Bobtsov, N Nikolaev, J Schiffer, D Dochain - Automatica, 2021 - Elsevier
In this paper we propose a new state observer design technique for nonlinear systems. It
consists of an extension of the recently introduced parameter estimation-based observer,
which is applicable for systems verifying a particular algebraic constraint. In contrast to the
previous observer, the new one avoids the need of implementing an open loop integration
that may stymie its practical application. We give two versions of this observer, one that
ensures asymptotic convergence and the second one that achieves convergence in finite …
