资源简介：
The goal of this experiment is to evaluate the tracking performance of the outer-loop actuator controllers in time domain.
Two predefined displacements are considered: a BLWN with a bandwidth of 0 to 5 Hz and a BLWN with a bandwidth of 0 to 15 Hz. During the predefined displacement commands, three MR damper specimen conditions are examined, including a 0.0 to 2.5 Amp pulse at 0.5 Hz and 50% duty cycle, constant 0.0 Amps, and constant 2.5 Amps.
