摘　　要：以高速电磁开关阀为控制元件,对轴向柱塞泵的数字控制进行研究。在实现轴向柱塞泵斜盘角位移控制的基础上,提出以轴向柱塞泵斜盘角位移控制为内环控制,流量、压力或者功率控制为外环控制的双闭环控制策略;在控制方法上,内环采用积分分离PID控制,外环采用两级模糊增量控制的控制方案。采用AMESim与MATLAB/Simulink的联合仿真,验证了所提出的控制策略和采用的控制方法的有效性,实现了轴向柱塞变量泵流量、压力和功率控制的快速性和稳定性。Based on angular displacement control, a dual-loop control strategy for the axial piston pump with high speed on-off solenoid valve was put forward, in which angular displacement control was as the inner-loop and flow, pressure or power control was as the outer-loop. Integral separation PID control algorithm was used to control the inner-loop and two-level fuzzy increment control algo- rithm was used to control the outer-loop. Co-simulation based on AMESim and MATLAB/Simulink shows that the method can be used to realize stable and rapid control of flow, pressure or power of axial piston pump.
