The damping capacity of driving mechanism is one of the important factor for the dynamic characteristics of position control system. Generally it is relatively low to realize the high gain position control system or to suppress the external vibration disturbances. But, there is no enough study on designing means to generate the suitable damping capacity intentionally. This study deals with the development and application of electrically viscous controllable dampers with Ferro Magnetic Fluid and Electro Rheological Fluid (ER fluid) to generate suitable damping capacity to feed driving mechanism. This report describes on the study of auxiliary mass viscous damper with FM fluid which only to fit driving ball screw end. After theoretical simulation with mathematical model and actual experiments, it can be verified that the damper is very effective to give suitable damping capacity intentionally to driving mechanism. Moreover, it also can be found design parameter tuning procedure which performs most effectively.
