Abstract

This paper presents a method of synthesizing an observer for a class of nonlinear systems. The method is based on the moving horizon estimation technique. It can transpose the observation problem into an optimization problem. It consists on the minimization of the difference between the system measurement and its prediction on a predetermined moving time horizon. The optimization algorithm used is ''Levenberg-Marquardt''. This methodology is applied to an example of CSTR chemical reactor.
