摘要
Time delay and its compensation are key problems for real-time hybrid tests (RHT). In a RHT system of MR dampers, the strong nonlinearity of MR damper causes time delay fluctuation of its loading system, the compensation effect of conventional time delay compensation methods for constant time delay systems is not enough ideal. Here, to solve this problem, an adaptive time delay compensation method based on model parameter identification was used to conduct RHT. Firstly, the principle of this method was presented. Then, numerical simulation for RHT of MR dampers and actual tests were conducted to verify the effectiveness of the adaptive time delay compensation method. © 2019, Editorial Office of Journal of Vibration and Shock.
