摘要
针对存在不同分布的路径约束与不同航程需求的升力式飞行器再入飞行任务,设计二次曲线形式的倾侧角剖面以增强飞行器的侧向机动能力,通过预测校正的迭代过程修正倾侧角剖面以满足航程需求,采用改进人工势场法设计侧向制导方法导引飞行器满足路径约束,最后通过粒子群算法优化制导参数以获得性能最优的轨迹.仿真结果验证了该算法能够适应多种航程需求与路径约束且以较高精度满足终端约束.
Abstract
To address the reentry missions with different path constraints and range requirements,a conic based bank angle is designed to enhance the lateral maneuverability,and the predictor-corrector guidance method is used to revise the bank angle profile to satisfy the range requirements.The improved artificial potential field method is used to design the lateral guidance method to satisfy the path constraints.Finally,the guidance parameters are optimized by particle swarm optimization algorithm to obtain the trajectory with the best performance.Simulation results verify that the algorithm can adapt various range requirements and path constraints,and meet the terminal constraints with high accuracy.
