Cooperative optimal mid-course guidance laws with parameter optimization

At present, there is no clear way to select the cooperative term coefficients in the cooperative guidance law based on the biased proportional guidance architecture, which is not conducive to project implementation. In this paper, considering the group cost function, an optimization method is proposed to solve the cooperative term coefficients of a cooperative guidance law. Firstly, the structure of cooperative mid-course guidance is introduced in three-dimensional inertial coordinate system. Secondly, the optimization method of the cooperative term coefficient is given and analyzed. Finally, numerical simulation results are given to illustrate the effectiveness of the proposed optimization method.
