RESUMO

This work proposes a parameter estimation method for nonlinear dynamical systems based on nonlinear control techniques and synchronization. The central idea of the method is to synchronize the model with the system, and, in parallel, to estimate the systems parameters. Synchronization is achieved by the use of nonlinear geometric control techniques, and the parameters are estimated using an adaptive method. The conditions for synchronization are studied, and the methods feasibility is evaluated using simulation examples with the Lorenz and R¨ossler chaotic systems.
