The performance of a satellite reaction jet attitude control system can be severely degraded by structural flexibility. Using a computer-modelled spacecraft with a pseudo-rate controller, a quantification of the performance loss is presented. Flexibility is introduced into the simulation in a very general way by reducing elastic interaction to a series of modal frequency and gain parameters. The modelled system is found to remain stable under all conditions studied, although performance may suffer various degrees of degradation. (Author)
