将飞机燃油消耗最小化问题表述为具有周期边界条件的最优控制问题。考虑两个问题：一个是飞机重量恒定的问题，另一个是飞机重量可变的问题。数值解是通过多次射击法计算的，并包括对功率设置的砰砰控制动作。与稳态解决方案相比，f -4型飞机的燃油消耗节省了大约2%。得到的解满足弱局部最优的二阶充分性条件。
The problem of minimizing fuel consumption of an aircraft is formulated as an optimal control problem with periodic boundary conditions. Two problems are considered: one with constant aircraft weight and one with variable weight. Numerical solutions are computed via a multiple-shooting method and consist of bang-bang control actions for power setting. In comparison to the steady-state solutions, savings in fuel consumption for an F-4-type aircraft are approximately 2%. The solution obtained is shown to satisfy the second-order sufficiency conditions for a weak local optimum.
