| Abstract: | In order to improve the reliability and environmental adaptability of rocket guidance, an online trajectory planning method based on convex optimization is proposed to achieve the original damage efficiency as much as possible. Taking the glide trajectory model of guided rocket as the simulation example and the trajectory planning model of optimal control energy as the research object, the standard convex optimization model is established by using the pseudo spectrum method to discrete continuous variables and linearize the nonlinear dynamic equations. The simulation trajectory is obtained by solving the convex optimization method and conducting cyclic simulation calculation, and compared with the original ideal trajectory. The simulation results show that the proposed method can quickly obtain feasible optimal trajectory when deviating from the preset initial trajectory, which proves that the proposed method is effective in solving trajectory planning problems when there is deviation.ξ |
