Abstract :
We provide a direct method for the construction of a change of coordinates for the design of nonlinear discrete-time observers. An explicit expression of a change of coordinates is given. Some simulations for chaotic systems, such as Lozi system and Henon system, are provided to illustrate the method. The proposed approach can be applied to continuous-time systems once the corresponding discretized structures are determined.
