Abstract: This study is concerned with the observer-based H-infinity stabilisation problem for a class of linear systems with large delay periods (LDPs). Based on the switching technique, the system with LDPs is modelled into a switched delay system which consists of two subsystems. The controller and observer gains are solved under the small delay case. Sufficient conditions are derived to ensure the system is not only exponentially stable, but also possesses an H-infinity performance index. The effectiveness of the proposed method is validated by the simulation of a load frequency control system.
