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,解决传统发动机间接推力控制精度低、响应慢的难题,提出了一种多伴随矢量发动机直接推力控制方法。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。该模型引入了稳态/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(MIMO)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<1 s、超调量<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。

Abstract:

To address the requirements of modern aircraft for high maneuverability and strong countermeasure capability in complex tactical environments, and resolve the drawbacks of low accuracy and slow response in conventional indirect thrust control of engines, this paper proposes a direct thrust control method for multi-companion vectoring engines. First, a nonlinear component-level model consisting of one main engine and two companion engines is established, with refined modeling conducted for key components such as the bleed air system. To achieve accurate estimation of engine thrust, an on-board adaptive model based on the Unscented Kalman Filter (UKF) is designed. This model incorporates a steady/dynamic discrimination logic to on-line identify the engine' s performance degradation parameters, thereby effectively suppressing the interference of flight dynamics on health assessment. On this basis, a data-driven Model-Free Adaptive Control (MFAC) strategy is further proposed, and a Multi-Input Multi-Output (MIMO) direct thrust controller is constructed to realize decoupled, rapid, and precise control of the thrust of the main and companion engines. Simulation results demonstrate that the designed on-board adaptive model can accurately track the actual state of the engine, and its thrust estimation results are highly consistent with the true values; the direct thrust controller responds rapidly, achieving stable and precise tracking of the commanded thrust under the conditions that the settling time of the main engine is less than 1 s and the overshoot is below 4%. This study provides an effective solution for the control system design of novel combined vectored-thrust engines and verifies the feasibility and potential of this scheme in improving engine control performance.
