| Abstract: | While a road simulation test is held,identification of the characteristics of the test system is one of the core steps for the success of the test ,which consists of vibration platform and the tested objects. The principles and process of the application of CARMA mo~lel to identify road simulation test system is discussed. Based on the CARMA model of SISO system in time domain,the model parameters and model orders by using the method of the union of system identification and optimum algorithm are given. And this method is proved to be correct by test data. |
