摘要: 以机载泵源系统的恒功率控制为目标,针对作业任务中系统负载随时间变化的情况,采用使液压系统输出功率保持恒定的控制方式来达到充分利用发动机功率的目的. 对于机载泵源控制系统的主要被控对象——轴向柱塞式变量泵,建立了其状态方程和流量输出方程,采用 H∞ 鲁棒镇定控制策略实时调节泵的排量.仿真结果表明:当负载变化时,系统能根据压力的变化快速转换到恒功率工作曲线下对应的流量状态,所设计的 H∞ 控制器能够减小干扰和模型参数不确定对系统稳定性的影响,具有良好的鲁棒性.表明该方法用于机载液压系统可以改善系统工作性能,提高系统功率的利用率.Abstract: Taking the constant power control of the airborne pump supplying as the goal, and addressing on the load variation during the process of the operation, the control strategy for keeping the output power constant to increase the utilization degree to the power of the engine was used. For the main controlled plant of the airborne pump supplying system with the variable displacement axial piston pump, the state space equation and flow output equation were built and the H∞ robust control strategy was used to regulate the flow of variable displacement pump. The simulation results show that the system could quickly return to a new flow state corresponding to constant power working curve when the load was changed. The H∞ controller can decrease the affections from the disturbance and uncertain parameters for the system stability and can be of a strong robustness. It could improve working performance and utilization degree of the system.
