Robust guaranteed cost resilient filtering for nonlinear uncertain systems with time delay

The problem of robust guaranteed cost resilient filtering design for nonlinear uncertain systems with time-varying delays is investigated. The nonlinear uncertainties are assumed to satisfy the norm-bounded conditions, and the uncertainties exit in both the system model and measurement output. The resilient filtering to be designed has multiplicative filter gain variations. The considered system is assumed to have norm-bounded parameters uncertainties. By using Lyapunov stability theory, the robust guaranteed cost resilient filtering design problem is represented in terms of linear matrix inequality (LMI). The parameters of the filter can be obtained by solving the LMI.
