High-rise building damping control method based on distributed fault diagnosis and collaborative fault tolerance

Abstract

The invention provides a high-rise building damping control method based on distributed fault diagnosis and collaborative fault tolerance. The method comprises the steps of firstly constructing a state space dynamic model of each floor of a vibrated high-rise building containing a damper fault; designing a corresponding distributed state observer and a corresponding adaptive fault diagnosis observer; then constructing a residual logic decision scheme based on residual signals generated by the distributed state observer and the adaptive fault diagnosis observer to judge which floor damper has afault; then acquiring state information of all floors; and designing a collaborative fault tolerance controller containing a collaborative compensation vector on the basis to ensure that the whole vibrated high-rise building can still maintain stability when the damper has a fault. The method provided by the invention can achieve the purpose of detecting and positioning the damper fault of the high-rise building, and especially can still perform damping on the building through collaborative fault tolerance when the damper has a fault and the building is subjected to large vibration, thereby ensuring the integrity of the structure, and then maintaining the stability.

Description

technical field [0001] The invention belongs to the technical field of fault diagnosis and fault-tolerant control, and in particular relates to a high-rise building shock absorption control method based on distributed fault diagnosis and cooperative fault tolerance. Background technique [0002] Typhoons, earthquakes, blasting, subway construction, passing traffic vehicles and other natural and human factors often cause vibrations in buildings. These vibrations will not only destroy the structural integrity of buildings, but also seriously threaten the health of people living in buildings. life and property safety. In particular, unpredictable earthquakes have typical characteristics such as suddenness, destructiveness, and difficulty in defense. Once they occur, no matter how strong the vibration is, it will affect the structure and appearance of the building, and cause certain physical damage to the occupants. and psychological harm. [0003] The traditional method of st...
