Delay-dependent robust stabilization of uncertain neutral systems with saturating actuators

摘要

The robust stabilization problem for neutral systems with saturating actuators is addressed here. The systems considered are continuous-time with parametric uncertainties entering all the matrices in the system representation. A saturating control law is designed and a region is specified in which the stability of the closed-loop system is ensured. The Lyapunov-Krasovskii functional is employed. The design is dependent on the time-delay and its rate of change. The controller is constructed in terms of the solution to a set of matrix inequalities by employing a descriptor model transformation of the system.
