EXPERIMENTAL VALIDATION OF A SIGNUM FUNCTION BASED DAMPER CONTROLLER FOR MR FLUID DAMPERS

摘要

Recently, Wang and Liao (2005) proposed a new damper controller for MR fluid dampers based on signum function and the control algorithm and simulation results are analyzed. In this paper, the experimental setup to validate the signum function based damper controller is established and the testing results are presented. The experimental results show that the signum function based damper controller for MR dampers can let the controlled damping force track the desired damping force very well and the effectiveness of the damper controller based on the signum function is verified.
