摘要

为应对现代飞行器在复杂战术环境中对高机动性与强对抗能力的需求,并解决传统发动机间接推力控制精度低、响应慢的难题,本文提出了一种多伴随矢量发动机的直接推力控制方法。首先,建立了由一台主发动机与两台伴随发动机组成的非线性部件级模型,并对引气系统等关键部件进行了精细化建模。为实现发动机推力的精确估计,设计了一种基于无迹卡尔曼滤波(UKF)的机载自适应模型。该模型引入了稳/动态判断逻辑,用于在线辨识发动机的性能退化参数,从而有效抑制了飞行动态对健康评估的干扰。在此基础上,进一步提出了一种基于数据驱动的无模型自适应控制(MFAC)策略,构建了多输入多输出直接推力控制器,以实现对主/伴随发动机推力的解耦、快速及精确控制。仿真结果表明:所设计的机载自适应模型能够精确跟踪发动机的真实状态,其推力估计结果与真实值高度吻合;直接推力控制器响应迅速,在主发动机推力调节时间小于1s、超调量低于4%的条件下,实现了对指令推力的稳定与精确跟踪。该研究为新型组合推力矢量发动机的控制系统设计提供了有效的解决方案,并验证了该方案在提升发动机控制性能方面的可行性与潜力。
