Abstract

Abstract: The control law synthesis method of the longitudinal DFBW system of a certain ACT demonstration aircraft is briefly described in the paper. The selection of the control law structure and parameter is also described. The control law includes the following functions: CAS, boundary (angle of attack and nominal load) limiter, RSS compensation and automatic trim. The function of filters and the attenuation of the self-excitation sustained oscillation are also discussed herein. The above design result is verified by the flight test.

Key words: design of control law, NSS, RSS, ACT
