摘要

This paper proposes a new integrative control logic for rapid maneuvering of a rigid satellite using reaction wheels. The proposed control algorithm is of a state feedback nature and is designed to accommodate a variety of conditions, such as the general three-dimensional direction of rotation, initial and/or final angular rates, general alignment of three or four reaction wheels, torque and angular rate limits, and system time response limits. Simulations indicate that the new algorithm allows smooth control, free of chattering. The new controller also uses a tuning capability to compensate for time delays and parasitic dynamics. The tuning capability can be varied in order to enhance performance or robustness. Robustness of the algorithm is proven through a stability analysis and supported by detailed and practical simulations.
