Electro-hydraulic Servo Position and Pressure Hybrid Control Method of Forepoling System on Tunnelling

Xie Miao;Liu Zhixiang;Chi Cheng;Mao Jun;Liaoning Technical University;Shenyang Branch of China Coal Research Institute;  
Taking into account the operational principles of forepoling equipment,and as the target to improve support efficiency and to reduce the disturbance on the roof in the process of supporting,a kind of speed and pressure composition control method was proposed.The control method adopted fuzzy switching controller to complete the conversion of electro hydraulic position and electro hydraulic pressure control.Theoretical analysis and experimental results show that,compared with the traditional speed and pressure control method,the control method herein can reduce concussion on the roof in the process of switching from speed control to pressure control,and can improve support efficiency.Research fruits can provide a theoretical basis for the research and control strategy of forepoling equipment.
