Network-based guaranteed cost tracking control for aero-engine

In this paper, we consider a class of uncertain systems with network-induced time-delay. The problem of designing state feedback guaranteed cost output tracking controller is investigated. A theorem dependent on network-induced time-delay, which is based on linear matrix inequality(LMI), is proposed for designing state feedback guaranteed cost controller. The optimal state feedback networked time-delay dependent on guaranteed cost control law is given. The error integral is augmented to the system model and the augmented system state feedback controller is designed to make the closed-loop system internal stable. Combined with the optimal guaranteed cost control, the optimal state feedback guaranteed cost tracking controller for uncertain system is obtained. In the case of a certain aircraft engine rotation system, simulation proves the above method is effective.
