Abstract

This paper discusses a control law design method for the flight control system of an aerospace vehicle in which control/structure coupling due to vehicle flexibility must be taken into account. Vehicle flexibility, or control/structure coupling instability, is one of the most important factors limiting the control performance of automatic flight control systems. This paper proposes an efficient approach for designing a rigid body motion flight control low and structural filter. The design method is an extension of the multiple-delay-model and multiple-design-point (MDM/MDP) approach developed by the author which obtains a rational trade-off between control performance and stability. A robust criterion for structure/control coupling stability is also proposed. This paper is a product of a review study of the Automatic Landing Flight Experiment (ALFLEX) program, which was conducted in 1996 as part of the development of a Japanese future reentry space vehicle. Lessons learned in the program are introduced to provide a background to this paper. The design method is applied to problems encountered during the vehicle's development, and the results are compared with the filter actually used in the vehicle's flight test.
