| 摘 要： | 首先建立了进行过失速机动时飞机的动力学数学模型,并在分析了模糊数学和模糊逻辑控制特点的基础上,设计了模糊逻辑控制器 ( FLC)应用于 2种典型的过失速机动 ( 70°迎角定常飞行和眼镜蛇机动 )的数字仿真。结果表明,采用模糊逻辑控制器,调整模糊控制器中有关参数或采用带修正因子的模糊控制器,能够使得飞机在更短的时间内完成过失速机动,同时改善了飞机的动态品质。

| Abstract: | This paper designed fuzzy logic controller (FLC) applying in numerical simulations of two typical post-stall maneuvers such as trimmed and sustained flight up to 70 degree angle of attack and Cobra maneuver, after a mathematical model of aircraft was established and the specialties of fuzzy mathematics and fuzzy logic control were analyzed .The results show that the character of the base fuzzy logic controller was improved by adjusting some factors of fuzzy logic controller such as scale factor and quantification factors, or introducing correction factors, and all these can make the aircraft complete these maneuvers in shorter time, and can improve the aircraft dynamic qualities. |

| Keywords: | fuzzy logic control thrust vector post stall maneuver Cobra maneuver dynamic qualities |
