Abstract：Aiming at the cooperative terminal guidance problem of hypersonic vehicles，a finite-time convergent adaptive sliding mode cooperative guidance method is proposed.This method simultaneously satisfies therequirements of terminal track inclinationangle，track azimuth angle，and time coordination.Finite-time convergent sliding mode cooperative guidance laws are designed separately for the dive plane and turning plane， and adaptive parameters of the sliding mode surface are incorporated into the guidance laws. For moving targets，coeficient compensation is applied to the relative track inclination angle between the vehicle and the targetto resolve the issue of sacrificing the strike angle to reduce miss distance when targeting moving objects. Simulation results indicate that the coperative guidance law enables each hypersonic vehicle to simultaneously satisfy therequirements offlight path angleconstraints，timing coordination，and their respective terminal track angle，exhibiting robustness against the deviation of initial states and aerodynamic parameters.
