The dynamic characteristics of the structure must be understood in order to design an efficient active seismic controller. Evaluating the parameters with precision is very crucial not only for accomplishing a low cost controller, but for preventing the structural control system from unstable behavior. These characteristics of the structures can be estimated from the measured input-output data called the system identification. The purpose of the study is to evaluate the feasibility of the system identification method used in mechanical and electrical engineering applications to apply for the building structures subjected to seismic disturbance. The result of study that ARX model, ARMA model, ARMAX model can be suitable model to apply for building structure in the system identification.
