Uspensky V. Precision orientation and stabilization system of a maneuver spacecraft

Research subject: controlled spinning process of an agile spacecraft using a gyro-power control system. Goal of the research: to improve methods and algorithms of gyro-power spinning control of a spacecraft to provide high precision and affordability of on-board control systems. Research methods: quaternion algebra, common mechanics methods, inverse dynamics methods, Lyapunov functions method, modal control methods, maximum principle, numerical optimization methods, numerical integrating. Theoretical and practical results consist of developing and proofing of a complex methodology for designing gyro-power orientation and stabilization control systems for spacecraft to provide long-range requirements to precision and affordability of functioning. Results that are obtained during dissertation accomplishment are used for development of orientation control systems for spacecraft "Arkon", spacecraft of "Spectr" line, spacecraft МС-2-8М. Scientific novelty consists of developing and using of generalized kinematical spinning models; nonlinear models, methods and algorithms for controlling of redundant gyrodines system; method for estimating moment of inertia of the spacecraft; method for an optimal discharging of a gyrosystem.
