Development of Acceleration Feedback Control of MRF Electro-Hydraulic Systems

Abstract

The electro-hydraulic valve is a mechanical component whose movements are directly influenced by electronic circuits. The characteristics and life of hydraulic directional control valves are affected greatly by moving parts. Using the rheological property of MR fluid, the new type MR flow directional hydraulic control valve can be designed with absence of moving parts. The problem of the conventional system is about the spool which is the response of spool is slow because of the friction between the cylinder. However this system do not have feedback control system yet. Thus study focus on developing the acceleration control system for MRF electro-hydraulic system. The system will be integrate by using matlab. The significant of this study is by using this system in the future, the MRF electro-hydraulic system will help people to use this further in the industry.
