Simulation and experimental analysis of a suspension system

This research was carried out to investigate the response characteristics of a two-degree of freedom (DOF) suspension system with the proposed active force control (AFC) as the main control element. Both simulation and experimental studies were carried out for this purpose. In the simulation study,...
