摘要
In this note, the differential game and dissipation inequality are applied to the disturbance attenuation or H-infinity-control for linear systems with delayed state. Firstly, a simple sufficient condition on the existence of a gamma-suboptimal H-infinity state feedback controller is given, which is independent of delay, and an observer-based dynamic output feedback solution is presented in terms of Riccati inequalities (or Riccati equations). Secondly, a sufficient condition on the existence of a delay-dependent state feedback is presented and the criterion is presented by a matrix inequality which can be solved by numerical methods.
