A hybrid control scheme of adaptive and variable structure for flexible spacecraft. (English) Zbl 1159.76378

Summary: For the control of a flexible space structure, in order to get both good dynamic characteristics and good static characteristics, a hybrid control scheme is put forward with a variable structure control method and an intelligent adaptive control method. The planar motion of a flexible structure is concerned with, which consists of a rigid central body and a flexible beam attached to it. In view of typical control requirements, a corresponding hybrid control scheme is developed. Finally, by comparing the simulation results of the hybrid control scheme and the variable structure control scheme, it is shown that both the dynamic characteristics and static characteristics of the hybrid control scheme presented in this paper are excellent.
