Piston Displacement Tracking of Hydraulic Propulsion System in Horizontal Well of Coal-bed Methane Based on Sliding Mode Control
According to the principle of similar hydraulic driving shield machine and electro-hydraulic servo valve,the AMESim model of the hydraulic driving system of coal-bed methane(CBM) horizontal well is designed and established.By introducing the sliding surface and the switching function of sliding mode control,a sliding mode control algorithm is proposed to realize the tracking control of the desired displacement.In this paper,the hybrid simulation combining Simulink controller and AMESim physical model is implemented for the simulation of the control of piston displacement tracking for hydraulic propulsion system.The simulation results show that the proposed algorithm has good tracking accuracy.
