Abstract

An input-delayed DTFTCS model in noisy environments with state feedback controller is developed. Delay-independent results are obtained using Lyapunov function approach and formulated as feasibility solution for a set of linear matrix inequalities (LMI). For a given state feedback gains, testable trackable sufficient conditions that guarantee the second moment stability and achieve delta-level of disturbance rejection are derived and proved. A numerical example is used to demonstrate the theoretical findings.
