摘要: 在全飞行包线内大机动飞行时,飞机的飞行参数变化剧烈,飞机模型呈现出严重的非线性,采用常规控制方法不能保证在整个飞行包线内均取得良好的控制效果.本文提出了一种新的模糊控制方法.该方法将模糊控制函数的优化和模糊控制系统增益自适应调整集中于一体,可大大改善系统的品质和适应能力.该方法已用于综合飞行/推力系统设计.数字仿真结果表明,这种新型的模糊控制方法取得了良好的控制效果.

Abstract: There is strong nonlinear in the model of an aircraft because flight parameters may change violently in the case of large maneuver flight within the full flight envelope. The traditional PI controller can not guarantee the good control performance within the full flight envelope. A new kind of fuzzy control method is presented in this paper. The fuzzy control method integrates optimization of fuzzy control function and self-regulation gain of fuzzy control systemadaptively in the control system, which could largely improve qualities and adaptability of control system. The new kind of fuzzy control method has been used in the design of integrated flight/pusher system of aircraft to control large maneuver flight. Considering the nonlinear six-freedom model of the aircraft and big maneuver flight, it is demonstrated by digital simulation that this new fuzzy control method gets good control results.
