介绍了空间小推力轨道优化问题中的最优Bang-Bang控制问题,对两类延拓解法给出了描述:第一类解法首先求解能量最优解,然后采用能量–燃耗同伦得到最优Bang-Bang控制;第二类解法引入推力开关切换准则,以双脉冲解作为初解,通过参数延拓得到最优Bang-Bang控制。对两类延拓解法进行了比较,指出了各自的优势与特点。对延拓方法应用于求解更加复杂的小推力轨道设计问题进行了展望,提出了包含初解、延拓与拼接三要素的人工智能轨道优化概念。
The optimal Bang-Bang control problem in space small thrust orbit optimization problem is introduced, and two types of continuation solutions are described: The first solution solves the energy optimal solution first and then uses the energy-fuel consumption homotopy Excellent Bang-Bang control; the second solution introduced thrust switch switching criteria to double pulse solution as the initial solution, through the parameter extension to get the best Bang-Bang control. The two types of continuation solutions are compared, pointing out their respective advantages and characteristics. The application of continuation method in solving the more complex design of small thrust trajectory is prospected, and the concept of artificial intelligence orbit optimization including initial solution, continuation and splicing is proposed.
