Dynamic output feedback satisfactory fault-tolerant control with constraints of consistent indices

The problem of dynamic output feedback satisfactory fault-tolerant control for linear continuous systems in the presence of parametric uncertainties is investigated. Based on a more practical and general model of actuator continuous gain faults, the closed-loop systems are guaranteed by the designed controller to meet the required constraints on regional pole index, steady variance index and H-infinity index simultaneously. Meanwhile, the consistency of the performance indices mentioned earlier is also discussed for fault-tolerant control. Furthermore, the effective dynamic output feedback satisfactory fault-tolerant controller design steps for systems with constraints of consistent indices are provided. A numerical example shows the validity of the proposed method.
