Force-Displacement Decoupled Control of Engineering Structures With Multi-Degree-Of-Freedom Testing
Abstract eng: Engineering structures sustains the spatial forces from the gravity, wind, earthquakes and so on. To examine the performance of such structural members, the forces in all six degrees of freedom(DOF) need to be exerted synchronously on the tested member. Because of the rigidity of the specimen, there are strong coupling effects among the six DOFs, which brings significant difficulty in the control of traditional linear actuators. To sovle this problem, the force-displacement double closed-loop hybrid control strategy is proposed in this study, by considering both mateiral and geometric nonlinearities. The proposed force-displacement decoupled control method is validated using a small scale specimen test, and the feasibility of this decoupling control method is proved by the test results.
