Nonlinear reduced-order observers based on the solution of Riccati equation

Abstract

The reduced order observer design problems of Lipschitz nonlinear systems are discussed. Thereduced orderobserverforLipschitznonlinearsystemisbasedon the solution of a Riccati equation. To examine the practical usefulness of the proposed observers, it is applied to a real robotic mode. The simultion results show that the proposed reduced order observer has good performances.
