摘　　要：针对高空台上流量调节阀在全包线飞行环境模拟过程中,因气动负载变化大而存在难以快速调节以伺服跟踪位置指令这一问题,提出一种考虑负载变化作用下电液作动机构的建模方法。对使用该方法建立的模型从两个方面进行仿真验证:首先将建立的变负载电液作动机构AMESim开环模型仿真结果与真实试验数据对比,两者相对误差不大于1.78%,验证了模型的准确性;其次在阀前、阀后气动压力干扰变化情况下进行闭环仿真,斜坡响应相对误差不大于1.26%,正弦响应相对误差不大于1.40%,验证了系统的伺服跟踪性能和抗干扰性能。In the simulation of the full-envelope flight environment,it is difficult to quickly adjust the flow regulating valve to follow the position command due to a large change in pneumatic load.In order to solve this problem,a modeling method for the electro-hydraulic actuation system in consideration of load changes was proposed.The simulation of the model built using this method was verified from two aspects.Firstly,the simulation results of the variable load electro-hydraulic actuator AMESim open-loop model were compared with the actual test data.The relative error was not more than 1.78%,which verified the accuracy of the model.Then closed-loop simulation was carried out under disturbance and variable front and rear pneumatic pressure.The relative error of the ramp response was no more than 1.26%,and the relative error of sinusoidal response was no more than 1.40%,which verified the servo tracking performance and anti-jamming performance of the system.
