MIMO SYSTEM IDENTIFICATION OF INDUSTRIAL BUILDING USING N4SID WITH AMBIENT VIBRATION

Abstract

The engineering buildings are industrial buildings that have high construction costs and are difficult to construct. In addition, these industrial buildings must be in safe condition both in terms of production contributions and the health of employees and should be under constant supervision. It is known that both economic and life losses in such structures will be higher. These structures constantly vibrate under internal and external loads and deform. Temperature changes and material fatigue as internal forces, wind loads as external forces, traffic loads, moving loads of machinery and equipment and earthquakes have negative effects on industrial buildings. For all these reasons, mathematical model should be put forward experimentally and in place by making system definition in industrial buildings. In this study, industrial building was used. In this study, Multi input-multi output (MIMO) system identification method was used. Results demonstrated that N4SID multi input-multi output (MIMO) system identification method is efficient and accurate in identifying modal data of the industrial buildings.
