Nonlinear Observer Design of the Generalized Rössler Hyperchaotic Systems via DIL Methodology

Abstract EN

The generalized Rössler hyperchaotic systems are presented, and the state observation problem of such systems is investigated.

Based on the differential inequality with Lyapunov methodology (DIL methodology), a nonlinear observer design for the generalized Rössler hyperchaotic systems is developed to guarantee the global exponential stability of the resulting error system.

Meanwhile, the guaranteed exponential decay rate can be accurately estimated.

Finally, numerical simulations are provided to illustrate the feasibility and effectiveness of proposed approach.
