【摘要】 本文基于非线性动态逆方法,引入飞行品质要求,设计了过失速机动飞行控制律,并在常规舵面和推力矢量的控制分配上,综合链式递增融合和最小能量融合的基本思想,形成了新的控制分配方案;在优化飞行控制律结构和参数实现最优控制性能的基础上,利用频响特性Bode图、尼尔——史密斯准则进行控制律的鲁棒性分析和综合评估;最后,进行"眼镜蛇"机动仿真,并在3D视景中直观显示,验证了控制律的效能,具有一定的工程应用价值。更多还原

【Abstract】 The paper uses nonlinear dynamic inversion combined with flight quality requirements to design flight control laws for a supermaneuverable aircraft,and introduces a new control allocation strategy in combination of aero control surfaces and thrust vectoring based on daisy-chaining algorithm and least-energy method.After Optimizing the configuration and parameters of the control laws,it uses several paragraphs to take robust analyse and Evaluation,with the employing of Bode diagram and Neal-Smith standard.It puts forward the cobra maneuver simulation with a 3D display at last.The simulation results show that the control laws perform excellently not only at the normal flight envelope but also at high angle of attack.更多还原
