Abstract

Abstract: Taking the research of nonlinear characteristics of the actuator loop as the point of departure, through the spectrum analysis and the experimental verification, the physical essence of control surface buffet excited by the high-treguency odd harmonic of the triangular wave in a high-gain fly -by-wire system has been discovered.The necessary condition of harmonic oscillation, as well as the frequency characteristics and the overcoming measures of the buffet in FBW system are also presented. These are important references for the designing of modern flight control systems.

Key words: ffy-by-wire system, triangular wave, oddorder harmonic, buffet
