Abstract
Stabilization of neutral systems with state delay is considered in the presence of uncertainty and input limitations in magnitude. The proposed solution is based on simultaneously characterizing a set of stabilizing controllers and the associated
admissible initial conditions through the use of a free weighting matrix approach. From this mathematical characterization,
state feedback gains that ensure a large set of admissible initial conditions are calculated by solving an optimization problem
with LMI constraints. Some examples are presented to compare the results with previous approaches in the literature.
