摘　　要：在飞机改装作业前需要通过多个千斤顶将飞机进行顶升。由于人工操作和千斤顶的液压缸中元件安装精度等会导致顶升过程中两侧位置不同步。针对飞机同步顶升过程的同步性及稳定性等问题,基于千斤顶中液压缸电液比例阀的数学模型,采用自抗扰同步控制策略,搭建双液压缸电液比例“主从”控制系统仿真模型进行研究。将“主从”自抗扰模型的仿真结果与传统PID控制仿真结果进行比较,结果表明:采用自抗扰控制器可有效减少主从双缸同步误差,实现对工况中扰动的补偿,提高顶升系统精度及抗扰能力。Before the aircraft modification operation,the aircraft needs to be jacked up by multiple jacks.Due to the factors such as manual operation and the installation accuracy of components in the hydraulic cylinder of the jack,the positions of both sides are not synchronized in the jacking process.Based on the mathematical models of the hydraulic jack in the process of anti disturbance,the active disturbance rejection synchronization control strategy was adopted,the electric-hydraulic proportional“master-slave”control system simulation model of the double cylinder was built to study the stability of the hydraulic jack in the process of anti disturbance.The simulation results of“master-slave”ADRC model were compared with those of traditional PID control.The results show that the auto disturbance rejection controller can be used to effectively reduce the synchronization error of the master-slave double cylinder,the disturbance in the working condition is compensated,and the accuracy and disturbance rejection ability of the jacking system are improved.
