Implementation of Precision Force Control for an Electro-Hydraulic Servo Press System

Based on the fuzzy method, a PC-based precision force control scheme is proposed for the electro-hydraulic 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...

Description
Summary:Based on the fuzzy method, a PC-based precision force control scheme is proposed for the electro-hydraulic 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 Lab VIEW for achieving the precision force control of hydraulic cylinder. In the experiments, 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.
