Abstract

Delay approach to continuous-discrete observer design for Lipschitz nonlinear systems is discussed. First, the convergence conditions of the nonlinear observer with a linear output correction are established in terms of linear matrix inequalities. In the second part of this note, new matrix conditions are derived to ensure the convergence of the hybrid observer with both linear and nonlinear correction terms.
