Abstract
This paper deals with the effect of known parameter errors on structural identification problems by using the estimation formula of confidence region. Numerical experimentation is conducted to examine the validity of the proposed method by mean of the sensitivity analysis of identified parameters with respect to model parameter errors and the propagation low of errors. In this paper, a method, which estimates the confidence region of identified parameters based on the concept of prior information about unknown model parameters, is proposed. The investigation of proposed method is performed by numerical simulation. The validity of the proposed method is verified with the numerical results.
