摘要

时滞及补偿问题是实时混合试验的核心问题。在磁流变阻尼器的实时混合试验系统中，磁流变阻尼器的强非线性导致加载系统时滞波动，适用于定时滞系统的常规时滞补偿方法的补偿效果不够理想。本文针对此类问题，采用基于模型参数识别的自适应时滞补偿方法开展实时混合试验。本文首先阐述了该方法的原理，并通过磁流变阻尼器实时混合试验的数值模拟及真实试验验证了方法的有效性。

Abstract

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.
