exponential nonlinear observer for parametric identification and synchronization of chaotic systems

this work proposes the use of a new exponential nonlinear observer for the purpose of parametric identification and synchronization of chaotic systems. the exponential convergence of the observer is guaranteed by a persistent excitation condition. this approach is shown to be suitable for a wide variety of chaotic systems. in order to illustrate the observer design procedure, several examples with simulation results are presented.
