Pseudo-dynamic testing method based on external displacement control Dapeng Wanga, Shizhu Tianb Suzhou University of Science and Technology, 1701 BinheRoad Suzhou 215011, Jiangsu, China awangdapeng@mail.usts.edu.cn, btianshizhu@mail.usts.edu.cn Keywords: external displacement control; closed-loop control; error compensation; PID parameters; pseudo-dynamic testing Abstract: In order to accelerate the velocity and improve the accuracy of the pseudo-dynamic testing, the external displacement control method is put forward based on the hardware control.
The shortcoming of the method is that the lower loading velocity will have some effect on the testing results of some structures with relatively high damping material, especially for the passive energy dissipation.

Therefore, DBD is gradually becoming the plasma science research hot spot[1].How to effectively observe DBD is one of the key technology research.
The first step is choosing particular kind of ultraviolet optical fibers(produced by Nanjing Diduo Science and Technology Company) and making them into optical fiber row by requirement.
This cover is made of metal material with the purpose of shielding magnetic field.
