摘要：This paper presents the design and application of an H-infinity fault detection and isolation (FDI) filter and fault tolerant controller (FTC) for structural vibration control systems with Active Mass Dampers (AMD). A linear matrix inequality (LMI) formulation is obtained to design a full order robust H-infinity filter to estimate faulty input signals. A fault tolerant H-infinity controller is then designed for the combined system of the plant and the filter. The controller minimizes the control objective selected in the presence of disturbances and faults. A building structure with an AMD is used in the validation of the FDI and FTC control design. The residuals obtained from the filter through simulation clearly identified the fault signals. The simulation results of the proposed FTC controller confirm its effectiveness for vibration suppression of the faulty control system. ? 2010 ASCE.
