摘　　要：针对煤矿井下泵房监控系统中的液位监控具有非线性、上升时间长与反应滞后现象的特点,提出了采用九点控制器的方法进行水泵控制,该方法是根据控制行为(偏差和偏差变化率)来调整控制器的输出,控制策略简单,仿真结果以及现场实际应用表明:九点控制器可以根据水仓工况和泵房实际操作情况控制水泵起停数量满足煤矿排水能力要求,提高了控制系统对井下涌水量变化的反应能力。In view of such shortcomings of liquid level monitor of monitoring system in pump station of underground colliery as nonlinearity,long risetime and lag response,nine-point controller was proposed to use to control the water pump.This method adjusted the output of controller according to control behavior（deviation and change rate of deviation） and had simple control strategy.Simulation results and field applications show that the nine-point controller can control the number of start-up and shut-down pumps according to the status of water reservoir and actual operation of pump station,which meets the drainage demands of colliery and improve the responsiveness of control system to the change of underground water flux.
