Abstract
In order to enhance the damping characteristics of Dutch roll mode and restrain sideslip during coor-dinated turning flight,based on the principle of state space feedback,the yaw damper is designed.Yaw rate,sideslip angle change rate and heading angle change rate are selected as feedback signals respectively in the two schemes,and high-pass and low-pass filters are added to form the aircraft yaw damping system.Firstly,the characteristic polynomial representing the transverse and heading modes is derived and analyzed.Then two con-trol schemes are proposed to analyze and design the control laws,and the national military standards and the design requirements of Boeing Company are introduced.Finally,a typical state point of a certain type of aircraft is selected,the linear equations of the aircraft are extracted by using the principle of small disturbance linear-ization,and based on the design requirements,the control law is designed and simulation comparison analysis is carried out by using the characteristic structure configuration method in modern control theory.The simulation results demonstrate that the yaw damper can effectively improve the Dutch roll mode damping characteristics and reduce the rolling ratio,ensure that the aircraft does not generate excessive sideslip angles during coordina-ted turning,and improve flight quality.关键词
