In this paper, the relative problem of simultaneous arrival of multiple missiles is investigated. Firstly, based on the geometric relationship between missiles and the target, the missiles-target engagement model is established. In order to accurately estimate the target acceleration information, a novel target acceleration estimator based on extended state observer (ESO) is designed, which can estimate the target accelerations along and orthogonal to the line of sight (LOS) and set the stage for the design of the guidance law. Furthermore, by using the Laplacian theory, the convergence performance of estimators is analyzed. Then, for achieving simultaneous arrival of missiles, the distributed cooperative control law based on consensus theory is proposed, which takes the relative range and velocity along the LOS as consensus error and can be applied to simultaneously intercept the unknown maneuverable target. Finally, simulation results are given to demonstrate the performance of estimators and the effectiveness of the proposed control laws.
