Summary:
This paper presents a methodology for designing an adaptive sliding mode observer to achieve synchronization of a class of nonlinear systems with unknown parameters. The observer’s states are driven by a sliding-mode error signal and the estimation of unknown parameters is updated according to a dynamic minimization algorithm. The convergence of the synchronization errors and parameter estimation errors has been justified by the conditional Lyapunov exponents and the effectiveness of the design has also been confirmed by simulations.
