Development of the robust algorithms and control system of technical state of construction objects

Narmin Eldar Rzayeva

Abstract


The object of the research is the technical state of the construction objects. The most problematic part of the task is the fact that with the use of existing traditional control systems based on known methods for calculating dispersion, correlation, spectral, static and dynamic characteristics, it becomes possible to detect only pronounced changes in the technical state of the controlled object. And this, in turn, prevents the timely conduct of an operational set of measures to prevent premature wear, damage and the appearance of defects. In the course of the research, technologies are developed for robust noise analysis of noisy signals received at the output of sensors installed in certain nodes of a construction object, as well as spectral analysis of noise. Due to the use of mentioned technologies, it becomes possible to eliminate the influence of noise on the adequacy of the results of monitoring and to conduct continuous control of the technical state of the construction objects in order to detect the latent stage of the origin of the changes, which is currently impossible with the application of existing algorithms and technologies. On the basis of stated technologies, the basic principles for the development of a system for the continuous control of the latent period of the origin of changes in the technical state of construction objects are proposed. Identification of the latent period of the origin of changes allows reducing material and time costs due to timely carrying out preventive maintenance work.
