Control Method and Controller Design of Hydraulic Pile Driver Fuselage Leveling

The hydraulic pile driver fuselage rapid precision leveling is key factor to ensure the working efficiency and pile quality. To meet the both aims of fast raise-fall and high-precision leveling during working, based on the study of fuselage leveling movement, this paper carried out control method study of hydraulic pile driver fuselage automotive leveling and designed a parallel controller based on PLC electro-hydraulic valve and proportional directional valve.
