Abstract : A theoretical analysis is given of linear multichannel control systems for vehicles orbiting in the atmosphere of the earth at supersonic velocities. A procedure is developed for obtaining a set of control system structures providing a selection invariance which can be used as a basis for the optimization of such control systems in terms of both quality and simplicity of realization. Equations describing the spatial motion of such vehicles and a graphic mathematical model of these equations are derived in the process. The methods of graph theory are applied in developing the algorithms for constructing such control systems.
