Abstract

Abstract Aiming to optimize the mode transition control schedule of the adaptive cycle engine (ACE), an optimization method based on a gradient algorithm was proposed. During the mode transition, the compressor surge margin, the total turbine inlet temperature and the combustion chamber fuel-air ratio are not exceeded. The integration of thrust by time was selected as the optimization objective. The geometric parameters were updated via the optimization target derivative. The speed limit of the geometric adjustment mechanism was also considered in the optimization process. The control schedules of two mode transition processes, from triple to double bypass mode and from double to triple-bypass mode were optimized. The optimization method presented in this paper can be applied to various mode transitions and the geometric adjustment speed meets all the constraints.

考虑几何调整速度的ACE模式转换控制方案优化

摘要针对自适应循环发动机(ACE)模式转换控制调度的优化问题，提出了一种基于梯度算法的优化方法。在模态转换过程中，压气机喘振裕度、涡轮进口总温度和燃烧室燃料空气比均不超过。选择推力随时间的积分作为优化目标。通过优化目标导数更新几何参数。优化过程中还考虑了几何调节机构的速度极限。优化了从三通到双通、从双通到三通两种模式转换过程的控制时序。本文提出的优化方法适用于各种模式转换，且几何调整速度满足所有约束条件。
