摘　　要：针对一类吸气式飞行器发动机工作时只有单边攻角特性的对象特点,提出一种下压段制导律设计方法。该方法采用BTT-180制导模式,同时在飞行器滚动过程中引入模糊控制,根据起控点的滚动角和滚动角速度优化滚动时间,提高滚动过程的平稳性。最后进行下压段制导律仿真分析,仿真结果表明该方法的正确性和可行性。同时该方法算法简单、自适应性强,具有较高的工程化应用价值。Regarding the attack angle characteristics of air-breathing vehicles, a driving down-phase guid- ance law is proposed. In the driving down-phase, The BTT-180 guidance law is applied. Aiming at enhan- cing the stability in 180-degree roll process, the fuzzy control method is utilized, which computes the roll- time based on roll angle and rate of the beginning controlling point. Then simulations are implemented for the driving down-phase guidance law, and the simulation results confirm its validity and rationality. Fur- thermore, the algorithm of this method is simple and practical so that it can be commendably applied in the engineering field due to its perspective value.
