摘　　要：在AEMSim仿真环境下,运用该软件内置的液压库、机械库以及相关模型库,构建液压缸的位置控制系统模型,通过调节仿真模型中各个部件的参数对液压缸活塞杆的位移进行仿真分析,绘制液压缸活塞杆的实际输出位移与期望位移和两者之差的仿真结果。结果表明:当增益4为250时,输出的位移与预期设置的位移之间的稳态误差是符合要求的,但动态跟踪误差超过了预期设定的范围,即超过了0.015 m;当增益4调整为500时,虽然动态跟踪误差满足要求,但稳态误差超标,超过了0.0005 m。所以增益值不是越大越好,而应该根据要得到的精度和具体要求进行实时调整,进而通过获得最佳的增益值来获得最佳的输出。研究结果为液压系统设计、后续评估及测试提供了参考。Under the AEMSim simulation environment,by using the built-in hydraulic library,mechanical library and related model library of the software,the position control system model of the hydraulic cylinder is constructed.By adjusting the parameters of each component in the simulation model,the displacement of the piston rod of the hydraulic cylinder is simulated and analyzed.The simulation results of the actual output displacement and the desired displacement of the piston rod of the hydraulic cylinder and the difference between them are drawn.The results show that when the gain of 4 is 250,the steady-state error between the output displacement and the expected displacement meets the requirements,but the dynamic tracking error exceeds the expected range,that is,more than 0.015 m;when the gain 4 is adjusted to 500,although the dynamic tracking error meets the requirements,the steady-state error exceeds the standard,exceeding 0.0005 m.Therefore,the gain value is not adjusted as large as possible,but should be adjusted in real time according to the accuracy and specific requirements,and then by obtaining the best gain value to obtain the best output..The results provide valuable basis for hydraulic system design and a reference for subsequent evaluation and testin.
