Tower Modal Parameters Identification Based on Polymax Method

Based on the background of a high tower structure under environment random excitation, large-scale complex system parameter identification based on Polymax method is presented in this paper. Firstly,the system of testing environment excitation response signal for large tower is designed.Secondly,the obtained signal is analysed and intercepted,then the ideal signals are selectted from each experiment. Lastly, the intercepted signal is identified for some parameters based on polymax method.The obtained result shows that the former is effective.
