State Estimator Design of Generalized Liu Systems with Application to Secure Communication and Its Circuit Realization

الملخص EN

The generalized Liu system is firstly introduced and the state observation problem of such a system is explored.

A simple state estimator for the generalized Liu system is developed to guarantee the global exponential stability of the resulting error system.

Applications of proposed state estimator strategy to chaotic secure communication, circuit implementation, and numerical simulations are provided to show the effectiveness and feasibility of the obtained results.

Besides, the guaranteed exponential convergence rate of the proposed state estimator and that of the proposed chaotic secure communication can be precisely calculated.
