Stabilization of linear systems with simultaneous state, actuation, and measurement delays
This paper considers the problem of stabilizing continuous-time linear systems with time delays. Specifically, a fixed-order (i.e. full- and reduced-order) dynamic compensation problem is addressed for systems with simultaneous state, input, and output delays. The principal result involves sufficient conditions for characterizing fixed-order dynamic controllers for delay systems via a system of modified coupled Riccati equations. The controllers obtained are delay independent and hence apply to systems with arbitrary unknown delay.
