巷道超前支架的电液伺服位置压力复合控制方法

摘要/Abstract

摘要：

考虑到综掘巷道液压迈步式超前支架的工作原理，以及超前支架在支撑过程中的实际工作特点，以提高支撑效率、减小超前支架在支撑过程对顶板扰动影响为控制目标，提出了一种电液伺服位置压力复合控制方法。该方法采用模糊切换控制器进行电液位置与电液压力控制的转换。对该方法进行了数字模拟仿真与样机模拟实验，理论分析与实验结果表明，该控制方法能够有效地使超前支架在从未支撑态以最快速度转换到支撑态，并且能够在位置控制与压力控制之间实现无冲击切换，以降低支架对顶板的扰动。研究结果为综掘巷道液压迈步式超前支架装备的研发及控制策略的研究提供了理论依据。

Abstract:

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.

Key words: forepoling, pressure control, position control, composite control, electro hydraulic servo, fuzzy controller
