The integration of adaptive cooperative control for position and attitude of distributed spacecraft

It is an important guarantee to ensure highly reliability, strong adaptability of distributed spacecraft that the adaptive cooperatives control for integration of the attitude and position. According to the performance requirement of the distributed spacecraft in the process of configuration adjustment, there is established a integration model of position and attitude based on dual quaternion, and design a cooperative controller based on sliding mode variable structure theory. Based on which we derive the adaptive cooperative control algorithm for distributed spacecraft integration of position and attitude by introducing the interference estimating algorithm through extended least squares method and weight algorithm of multi-spacecraft's state. Finally, mathematical simulation has been done to verify the stability and efficiency of the designed controller. The adaptive cooperative control algorithm for distributed spacecraft covers integration of position and attitude, collaboration requirement of multi-spacecraft and environment interference, and also ensures the performance for its efficiency, stability, and cooperation, which enhances system's control ability.
