ABSTRACT In this paper, a prescribed‐time cooperative integrated guidance and control (PTCIGC) is designed for reentry vehicles to achieve cooperative guidance and control. This method is designed based on bank‐to‐turn and skid‐to‐turn (BTT‐STT) hybrid control strategy. Firstly, an IGC model of the reentry vehicle is established, which can be divided into three subsystems: Relative motion subsystem, airflow angle subsystem, and three‐channel angle rate subsystem. Secondly, a prescribed‐time controller is designed for the relative motion subsystem to obtain the airflow angle commands. Thirdly, a prescribed‐time sliding mode controller (SMC) is designed for the airflow angle subsystem to track the airflow angle commands. Fourthly, to track the three‐channel angle rate commands, a prescribed‐time disturbance observer (DO) based on prescribed‐time SMC is designed. Finally, the effectiveness of the PTCIGC method proposed in this paper is verified by six‐degree‐of‐freedom (6DoF) numerical simulation in three‐dimensional (3D) space.
