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.

Key words

positive displacement feedback / displacement control / force control / switch control
