Design of Fault Detection and Isolation for Active Structural Control System Based on LMI Approach
This paper proposes the fault detection and isolation (FDI) technique and presents the design method of FDI filter in active control system of structure based on H∞ robust control theory. The FDI system model is constructed according to H∞ object which changes the fault detection problem to a robust control problem. The H∞ optimal controller named FDI filter is worked out by linear matrix inequality (LMI). Simulation results for a three-story building demonstrated the effectiveness of FDI filter. This paper can provide a reference for the structure health monitoring of active control system and is the base of the fault tolerant control.
