A direct method for the construction of nonlinear discrete-time observer with linearizable error dynamics
We provide a direct method for the design of nonlinear discrete-time observers by a construction of a change of variables. An explicit expression of the change of variables is given. Some simulations for chaotic systems, such as Lozi system and Henon system, are provided to illustrate the proposed method.
