摘　　要：根据煤矿井下工作面液压支架安装搬运的技术要求,提出了一种采用电液比例技术驱动控制的液压支架搬运系统。该系统采用电液控制技术,采用电液比例变量泵控马达闭式容积调速回路系统作为液压支架搬运系统的动力驱动方案。运用Matlab软件对系统进行了仿真。为了进一步改善系统的稳定性和快速性,提出了基于遗传算法的PID校正控制方案。仿真结果表明,校正后的系统具有较好的稳定性和控制效果。Abstr act： According to the requirements of the working face of the coal mine hydraulic support installation and dismantle mechanization process, a novel kind of hydraulic support handling technology based on electro-hydraulic proportional control system is proposed. The hydrau lic drive system with proportional control technology uses the closed volume control circuit system of the electro-hydraulic proportional variable displacement pump control motor as the driving scheme of the hydraulic support transportation vehicle system. The Matlab software is used for the system simulation. In order to improve the stability and fast performance of the system, a genetic algorithm based PID correction control is presented and the simulation results show that the system has good stability and better control performance after correction.
