H ∞ filter design for a class of delayed Hamiltonian systems with fading channel and sensor saturation

This technical note is concerned with the problem of H∞ filtering for a class of time delay nonlinear Hamiltonian systems with wireless network communication. The fading channel phenomenon and sensor saturation in the output measurements are considered. A H∞ filter model is constructed to solve the issue of state estimation for the Hamiltonian systems with time varying delay in the state. Some sufficient conditions are proposed to obtain effective filter gain and achieve the H∞ performance for the augmented system consisted of the Hamiltonian system and the filter. Simulation results illustrate the validity of the main results.
