摘要：The Parallel Genetic Algorithm (PGA) is applied in this paper to solve the reentry trajectory problem of spacecraft. First, the time variable t in motion equations of spacecraft is replaced with velocity v, which can increase the robust of the solution and reduce the computation cost. Second, the control inputs are constructed with the inspiration of proven methods. Finally, PGA is applied to find one global optimization solution. The optimal trajectory is obtained with this method and the result is pretty good comparing with other methods.
