Research for energy consumption reduction of tri-axis satellite antenna

As the use of tri-axis remote sensing satellite is increasing, energy consumption is going high. The paper briefly describes the composition and function of the antenna control system. To deal with this situation, the power test data is employed to analyze the energy consumption of tri-axis remote sensing satellite antenna. Besides, from the aspects of shortening the closed loop waiting time of antenna, a tri-axis to brake, strategies and measures are discussed to reduce energy consumption. An intelligent torque bias control is designed to reduce the torque bias value. Therefore the energy consumption of equipment can be effectively controlled and reduced.
