Abstract

The invention provides a sensor fault and structure damage identification method based on improved adaptive particle filtering. The method comprises the following steps: S1, forming a structure damageidentification model and a sensor fault diagnosis model according to physical characteristics of a civil structure, a finite element model or a system identification method; S2, processing data collected by the sensor by applying the two equations and improved adaptive particle filtering to obtain structure parameters and sensor parameters; And S3, directly obtaining the specific condition of thesensor fault or the structure damage through the parameters.

Description

technical field [0001] The invention relates to the fields of civil engineering and computer, and relates to a sensor fault and structural damage identification method based on improved self-adaptive particle filter. Background technique [0002] In recent years, due to the rapid development of engineering structure health monitoring systems, more and more large-scale civil structures are equipped with sensors, and we use the data measured by sensors to evaluate the safety and reliability of structures. Generally speaking, the service life of the structure is as many as decades or even hundreds of years, however, the service life of the sensor is shorter, only a few years. Therefore, during the operation of the health monitoring system, there will inevitably be sensor failures. Table 1 shows several common sensor failure models, where y k , are the actual output value and the real output value of the kth time step, respectively, w k is the measurement noise at the kth ti...
