摘要
介绍了现代战术飞机自修复飞行控制研究方法,针对某型飞机的特定飞行状态与机身损伤故障模式,建立飞行与控制数学模型,采用仿真方法对比研究了在模型精确和有误差情况下伪逆法重构飞行控制律的效果.结果表明:应用伪逆法重构飞行控制律对精确模型具有反应快速的优点,但对模型误差鲁棒性不强,不能单独应用.
The paper introduces the methodology of self-repairing flight control system. The specific flight dynamic and control system models of a aircraft with a horizontal tail damaged in some degree are presented. The effect of flight control laws reconstructed by pseudo-inverse method separately based on precise and imprecise model is compared with numerical simulation. The results show that pseudo-inverse method is not robust to model errors, and expects to be improved for practical flight control system design.
