大型飞机迎角/过载限制器设计

AOA/NA Limiter Design for Large Transport Category Airplanes

根据典型大型飞机迎角/过载限制器的特点,提出了两种采用积分控制来减小静态误差的大型飞机迎角/过载保护方法,即最大值切换逻辑和加权过渡逻辑方法,深入研究了如何设计迎角/过载限制器参数,探讨了采用以上两种不同方法来进行迎角与过载限制器切换的优劣,系统仿真结果证明了所设计的限制器的有效性。该项研究为我国未来大型飞机如何设计迎角/过载限制器提供了部分理论依据。

On the basis of the different characteristics of an AOA/NA limiter for several classical large transport category airplanes, two new schemes of the AOA/NA limiter for large transporters which minimizes the steady tolerance by using an integral controller were suggested. Furthermore, how to design controller coefficients of the AOA/ NA limiter was deeply explored. In addition, the different influence to plane＇ s response by using the MAX logic switcher and smooth transition switcher was analyzed. The effectiveness of the AOA/NA limiter designed by the methods suggested, was proved by computation and simulations finally.
