【摘要】 再入飞行器横向机动能力分析可以描述为一个具有多约束的最优控制问题,不便于求解。本文将控制量攻角和倾侧角同时离散化,把约束最优控制问题转化为约束参数优化问题;推导了攻角的取值范围,缩小了搜索空间,降低了问题的复杂性;用改进的约束DE算法求解该优化问题。以X-33为例对算法进行仿真验证,仿真结果表明所提算法能够很好的处理约束,且优化结果的鲁棒性较好。更多还原

【Abstract】 Lateral maneuver capacity of reentry vehicle analysis can be formulated to a multi-constraints optimal control problem which is difficult to solve.We transform the infinite dimensional optimal control problem to parameter optimization which is finite dimensional by discretize control parameters.In order to simplify the problem,we figure out the control parameter’s scope by process constraints.To handle constraints,we proposed a parameterless constraints handle process incorporated to DE.It is validated by a reentry vehicle X-33,simulation results indicated that the algorithm is effective and robust.更多还原
