A new type of impulsive observer for hyperchaotic system

This paper proposes a new observer scheme for chaotic and hyperchaotic systems. Firstly, a classical impulsive observer is investigated for Lorenz chaotic system. This approach is based on sufficient conditions for stability of impulsive dynamical systems. After, an hybrid observer is proposed for hypoerchaotic systems. Simulation results highlight the well founded of such observer design and show that the discrete measurement may be eventually sparse.
