Gyrostat Orientation With Variable Moment of Inertia
The article examines a problem of a singleaxis and a triaxial orientations of the gyrostat system with inertia moment of carrier wich depend on time (a variable structure). The orientation is researched relatively Koenig’s coordinate system and a random noninertial coordinate system. The problem is solved analytically by the active control construction applied to the system of bodies on the principle of feedback. The stabilizing control and conditions providing a possibility of desired orientation are obtained. This orientation has a property of an asymptotic stability. The assigned task was being solved on the basis of the Lyapunov’s functions method and a method of limit equations and systems which enable to use the Lyapunov’s functions which possess constant signs derivatives. Gyrostat, program motion, functions with a constant signs, lyapunov's function, asymptotic stability.
