To improve the rapidity and accuracy of receiver aircraft tracking rendezvous, an design method of integrated guidance and control (IGC) for aerial refueling based on sliding mode is proposed. To link the guidance and control loop, a sliding mode surface is used to integrate multiple intermediate control variables to convert the guidance command into the required control surface input. Compared with the traditional independent design method of guidance and control, the integrated design of guidance and control can effectively improve the tracking performance of the receiver aircraft and shorten the time required for rendezvous and docking. The results show that the design method has a certain reference value for the development of aerial refueling system.
