摘要

为了结合力控制与位移控制两种不同试验加载控制模式的优点，并在拟动力试验中实现两种模式的自动切换，提出了基于位移正反馈的力与位移切换控制方法。首先从理论角度分析了切换控制过程，然后从数值模拟和试验角度分别验证了该方法的可行性和有效性。研究结果表明，该方法能很好地实现力与位移控制模式之间自动而平滑的切换。

Abstract

A force-displacement switching control method based on the positive displacement feedback loop is proposed in order to combine the advantages of the force control mode and the displacement control mode and to accomplish automatic switching in pseudo-dynamic testing. Firstly, the switching process is theoretically analyzed. Numerical simulations and test results demonstrate that this method can provide automatic and smooth switching between force control and displacement control.
