Implementation of fuzzy force control for an electrohydraulic servo press system

Abstract

In this chapter, based on the fuzzy method, a PC-based precision force control scheme is proposed for the electrohydraulic servo press system. The main feature of proposed scheme is to develop a composite control of relief valve and flow servo valve. With the feedback of force sensor, the fuzzy-based control system is realized by LabVIEW for achieving the precision force control of hydraulic cylinder. In the experimental testing, a practical platform of hydraulic servo press system is used to demonstrate the effectiveness of proposed scheme. The testing results indicate the accurate output responses. © 2013 Springer Science+Business Media New York.
