摘　　要：为了抑制飞机耗氧型燃油惰化系统整体式反应器内飞温现象的发生,为提升工作效率,延长使用寿命,利用Modelica语言对整体式反应器建立双温度模型,开展动态仿真,并设计了逆流式冷却措施。根据反应器温度特性,制定了相对应的控制策略,建立模糊控制器,研究了不同工况下模糊控制器在逆流式反应器温度控制上的工作特性,以及冷却管道排布对反应通道工作效率的影响。研究结果表明:模糊控制对逆流式反应器温度控制稳定性较好,有效抑制了反应器尾部的飞温现象;相比无温控管道,单侧和双侧存在温控管道时,单根反应通道的平均反应速率分别提升了1倍和10倍,添加温度控制后,反应器整体燃油蒸气转化率从10%提升至99%。隶属函数方差σ^(2)对控制效果有明显的影响,方差σ^(2)越大,控制精度越低,响应速度越快,要根据不同进口状态选取合适的σ^(2),以获得最佳控制性能。To restrain high temperature in specific area in monolithic catalyst in oxygen-consumption based inerting system,promote efficiency and extend service life,a bi-temperature catalyst model is built with Modelica and dynamic simulation is proceeded.A Cooling measure based on reversed flow reactor is designed.A fuzzy control system is established according to catalyst temperature character.The operating characteristic of this fuzzy control on reverse-flow under different condition and reaction tunnel working efficiency under different cooling tunnel distribution is studied.Result shows that this fuzzy control system can restrain high temperature efficiently with good stability.Average reaction rate of single reaction tunnel with one-side and two-side temperature control tunnel rises 1 times and 10 times.Overall conversion rate of fuel steam with temperature control promotes from 10%to 99%.Varianceσ^(2)of membership function obviously influences the control system performance.Greater variance leads to faster response speed and less accuracy.Appropriateσ^(2)should be chosen according to different inlet condition to obtain best control performance.
