Estimation and control of a class of Euler discretized nonlinear systems

We deal with the observer and controller design for Euler discretized form of nonlinear systems. Busawon et al. (1993) treated the problem of digital implementation of the high gain observer given by Gauthier et al. (1992) via a simple forward Euler discretization scheme. De Leon-Morales et al. (1998) investigated the digital implementation of a high gain controller via a similar forward Euler discretization scheme. It is shown that the result is dual to that given by Busawon-Saif-Farza (1997). In this paper, the observer and controller design based on some of the results from Busawon et al. (1998) for the Euler discretized version of nonlinear system is treated
