轻型公务机迎角限制系统设计与飞行品质评估

Design of angle limit system of a business jet aircraft and flying qualities evaluation

设计了基于C*响应的某轻型公务机的纵向控制增稳系统,为了飞行安全,采用闭环控制方法设计了迎角限制器,并对迎角限制系统与控制增稳系统模态兼容问题进行了研究,实现了模态平滑转换,最后对飞行品质进行了评估。系统数字仿真结果验证了迎角限制的有效性。

A longitudinal control augmentation control system based on the C ＊ response was designed. For the flight safety, angle of attack limiter was designed by using the closed loop control method,and the compatibility problem of the modal between angle limit system and control augmentation system was studied,smooth transition of the model was realized. Finally, the flying qualities were evaluated,system digital simulation results demonstrated the effectiveness of a limit on the angle of attack.
