Paper Abstract

An integrated trajectory optimization method for strong coupling and multi-constraints vehicle is presented. Based on the characteristics of strong coupling and multi-constraints, considering the change rate of angle of attack and safety margin of scramjet as additional constraint conditions and taking the minimum coupling degree as optimization index, the reference trajectory is adopted, which uses a smoothing method for solving multi-constraint s optimal problems. The reference trajectory can avoid the scramjet being in unsafe working condition to a certain extent, and also can greatly improve the accuracy of reference trajectory tracking. Based on the precise simulation model, the simulation analysis is carried out. The simulation results show that the method is effective and reliable.
