measured by a linear variable differential transformer (LVDT). Control sig-
nal is generated from a computer data acquisition (DAQ) system, and this
signal is feedback to the current amp and applied to the MR damper.
Figure4.27 presents the damping force control results under sinusoidal
desired damping force. Figure4.27(b) shows the magnication graph of (A)
in Figure4.27(a). It is seen from the control results that the proposed control
algorithm with hysteretic compensator gives more accurate damping force
control performance than without the hysteretic compensator. I
