Based on a recently developed approach to the design of unknown input observers, this paper presents a general structured unknown input observer(GSUIO)-based fault detection approach for control system. It develops a full-order general structured unknown input observer for fault detection by employing the generalized inverse of matrices,the {1}-inverse,in which the residual is designed to be insensitive to unknown disturbances,whilst sensitive to faults. The residual can be used to detect faults according to a simple threshold logic. The method is used to detect faults in actuator and component of the tilting control system in tilting train. Simulation results show the efficiency of the method. The foundation of designing methods of tilting trains is set up.
