    • An electrohydraulic system for control of a variable output pump includes a microprocessor-based controller receiving inputs from condition sensors coupled to the pump and command inputs from a remote master controller. The controller supplies outputs to an electrohydraulic valve for metering hydraulic fluid to a pump control port and thereby controlling pump operation in any one of a number of preselected and prestored pump control modes. A hydromechanical valve is connected in parallel with the electrohydraulic valve for controlling pump operation in the event of electrical malfunction or failure. Circuitry connected between the pump condition sensors and the control computer prevents aliasing errors due to mismatch between the computer sampling frequency and pump speed.
    • 用于控制可变输出泵的电动液压系统包括基于微处理器的控制器,其接收来自耦合到泵的条件传感器的输入和来自远程主控制器的命令输入。 控制器将输出提供给电动液压阀,用于将液压流体计量到泵控制端口,从而在多个预选和预存的泵控制模式中的任何一个中控制泵运行。 液压机械阀与电动液压阀并联连接,用于在发生电气故障或故障的情况下控制泵的运行。 连接在泵状态传感器和控制计算机之间的电路防止了计算机采样频率和泵速之间的不匹配导致的混叠误差。
