    Abstract: A pump control system, comprising: a motor (12) configured to drive a pump (14); a pressure relief valve (22) in fluid communication with the pump (14); a torque control valve (32) connected to a swashplate of the pump (14) and in fluid communication with the pressure relief valve (22); a swashplate angle sensor (36) connected to the swashplate (34); and a computer (40) connected to the swashplate angle sensor (36) and the pressure relief valve (22) wherein the computer (40) controls the pressure relief valve (22) based upon swashplate displacement to achieve maximum system pressure. The corresponding method of controlling is also disclosed.

    Abstract translation: 一种泵控制系统，包括：电动机（12），构造成驱动泵（14）; 与所述泵（14）流体连通的减压阀（22）; 与所述泵（14）的斜盘连接并与所述减压阀（22）流体连通的扭矩控制阀（32）; 连接到斜盘（34）的斜盘角度传感器（36）; 以及连接到斜盘角度传感器（36）和压力释放阀（22）的计算机（40），其中计算机（40）基于斜盘位移来控制泄压阀（22）以实现最大系统压力。 还公开了相应的控制方法。
