Abstract :
To meet the requirement of the earth surface level variation during tunnel boring, electro-hydraulic proportional push system with flow-pressure control, theoretical analysis and simulation of this push system are carried out. The use of conditional jump calculus in this paper can improve the stationary control accuracy of the electrohydraulic proportional velocity regulating valve significantly.
