Robust Controller Design for Large-scale Neutral Distributed-time-delay Systems

Linear time-invariant neutral large-scale distributed-time-delay systems, composed of a number of overlapping subsystems, are considered. First, a robustness bound for such systems is derived. Then, a robust controller design approach, using this bound, is proposed. Excluding the derivation of this bound, the controller design is independent for each subsystem and is based on a local nominal model. Robust stability of the overall actual controlled system, however, is assured, once a scalar condition, which involves the derived bound, is satisfied.
