本文着重阐述了飞机横侧向等效系统拟配形式的确定及在拟配过程中的一些规律。由于引入了低阶等效基的概念,更加明确地说明了各种匹配形式的使用条件。文中讨论了各种环节对等效参数的影响,对带有前置滤波器的控制系统的匹配中存在的问题,作了圆满的解释,并对求得的等效时间延迟提出了修正方法,对时间延迟作了更细的划分,说明了拟配中出现负时间延迟对飞行品质的影响。
This article emphatically expounds the determination of the fitted form of the lateral equivalent system of the airplane and some rules in the process of fitting. Due to the introduction of the concept of lower order equivalent basis, the conditions of use of various matching forms are more clearly described. In this paper, the influences of various links on the equivalent parameters are discussed, the problems existing in the matching of the control system with the prefilter are satisfactorily explained, and the correction method of the equivalent time delay is proposed. The time delay has been more detailed division, indicating the negative impact on flight quality caused by the delay of negative time.
