The invention provides a double-pump separate-cavity adjusting control load simulation system. The double-pump separate-cavity adjusting control load simulation system comprises a simulator loading system and a steering engine system, and the simulator loading system comprises two hydraulic pumps, a loading actuator, a speed sensor and a force sensor. Two bidirectional metering pumps are separately connected with two cavities of the loading actuator, so that the flow or pressure of the two cavities of the loading actuator is adjusted, each bidirectional metering pump has two working modes including a flow control mode and a pressure control mode, a controller can generate a loading control instruction based on a load spectrum instruction and a force sensor feedback signal, the bidirectional metering pumps in the pressure control modes are adjusted, and the regulation and control on the pressure state of one cavity of the loading actuator are realized; and the controller can further generate a speed control instruction based on a speed reference instruction generated on line and a speed feedback signal of the loading actuator, and the flow state of the other cavity of the loading actuator is adjusted by adjusting the bidirectional metering pumps in the flow servo mode so as to decouple active motion interference of a steering engine.

    本发明提供一种双泵分腔调节控制负载模拟系统,包括模拟器加载系统和舵机系统,模拟器加载系统包括两个液压泵、加载作动器、速度传感器和力传感器,两个双向定量泵分别与加载作动器的两腔连接,以调节加载作动器两腔的流量或压力,每个双向定量泵有流量控制模式和压力控制模式两种工作模式,控制器可以基于载荷谱指令和力传感器反馈信号生成加载控制指令,通过调节处于压力控制模式的双向定量泵,实现对加载作动器一腔压力状态的调控;控制器也可以基于在线生成的速度参考指令以及加载作动器的速度反馈信号生成速度控制指令,通过调节处于流量伺服模式的双向定量泵,对加载作动器另外一腔的流量状态进行调节,以解耦舵机的主动运动干扰。
