摘要
基于AMESim仿真平台搭建了油箱惰化空气预处理系统性能仿真模型,建立了飞机飞行状态参数模型,通过改变换热器换热效率、涡轮流量等参数对系统进行动态优化仿真分析,得到了适用于全飞行剖面的性能模型,保证空气预处理系统在飞机起飞、爬升、巡航、下降等所有飞行阶段,出口温度能够控制在75℃±5℃温度范围内。基于仿真模型,对控制模型的PID参数进行优化,提升了系统出口温度调节的收敛速度。提出的仿真分析方法对空气预处理系统的参数分配及控制率的研究具有一定的指导意义。
Based on the AMESim simulation platform,the performance simulation model of the fuel tank inerted air preparation system is built,and the aircraft flight state parameter model is established.The dynamic optimization simulation analysis of the system is performed by changing the heat exchange efficiency of the heat exchanger,the turbine flow rate and other parameters.The performance model of the full flight profile ensures that the outlet temperature of the air preparation system can be controlled within the range of 75℃±5℃during all flight stages such as take-off,climb,cruise,and descent of the aircraft.Based on the simulation model,the PID parameters are optimized,and the convergence speed of the system outlet temperature adjustment is improved.The proposed simulation analysis method has certain guiding significance for the research of the parameter allocation and control rate of the air preparation system.
