Abstract

This paper presents an electro-hydraulic control system for shield thrust drive. The control model of thrust system is developed. A pressure and flow compound control approach is applied using the pressure and flow rate feedback to design an outer loop controller and an inner loop controller to address the control problem encountered in thrust, cooperating with the pressure relief valve and the flow control valve. Simulation and field application results are presented to verify the effectiveness and rationality of the proposed drive system and its control approach.
