For the space assembly formed by the service spacecraft capturing the target spacecraft, considering the unknown quality characteristics of the target spacecraft and unknown combination dynamics model, the model-free data driving control method is introduced into the space assembly orbit and the field of attitude control, and a dynamic linearization "generic function" is proposed to characterize the excitation response relationship of space assemblies. Then a data drive controller is designed based on this "generic function". Because this controller does not rely on the dynamic model of the assembly, it can solve the control problem of space service spacecraft with complex dynamic, timevarying dynamic parameters, and strong dynamic coupling. In this paper, the designed controller is verified by digital simulation, which proves the effectiveness and accuracy of this method.
