摘要：
A waypoint tracking approach combined with geometric dynamics and a simplified strategy for no-fly zone constraints are proposed to address the complex environmental constraints in the trajectory planning of hypersonic glide vehicles. Firstly，based on the variation range of heading angle during flight determined through a flight corridor，a cost function is designed using angles as the index，and the flight state is predicted through optimization to obtain the lateral maneuver model of bank angle adaptive search. Secondly，the strategy of generating virtual waypoints on the geometric plane is extended to the Earth’s surface，and a generation strategy of global optimal virtual waypoint is derived based on graph theory and dynamic evaluation models. Finally，the two methods are combined to obtain a trajectory planning method that can handle multiple no-fly zone constraints. Simulation results show that the proposed method can quickly and effectively acquire the optimal virtual waypoint and reduce the difficulty in optimizing the bank angle during trajectory planning. Monte Carlo simulation experiments show that this method has good robustness. © 2023 AAAS Press of Chinese Society of Aeronautics and Astronautics. All rights reserved.
