建筑抗震实时混合试验时滞补偿方法研究综述

Review of Delay Compensation Methods for Real-time Hybrid Testing of Earthquake-resistance of Buildings

时滞补偿是建筑抗震实时混合试验的重要问题。文章对时滞补偿方法的研究进行总结,将时滞补偿方法分为基于时间的位移预测时滞补偿方法、基于反馈力的位移预测时滞补偿方法、基于加载系统模型求逆的时滞补偿方法、基于控制理论的时滞补偿方法和基于集成理念的综合补偿方法。

Time-delay compensation is an important problem in the real-time hybrid seismic testing of buildings.In this paper,research on time-delay compensation methods are summarized and these methods are divided into time-based displacement prediction,displacement prediction based on the feedback force,methods based on loading system model inversion,methods based on control theory,and comprehensive compensation methods based on concept integration.All of these methods are introduced and described.
