The optimal high altitude guidance law with reentry constraint condition is derived by using the optimal control theory, and the algorithm of time to go is also given.
给出了一种新的飞行器运动数学模型和这一模型下的最优制导律以及再入飞行器发动机工作时间、过载系数和估算方法。
Because the time constraint of the real-time tasks, the scheduling algorithm must incorporate the fault-tolerance technique, for preventing from the task failure under the condition of system faults.
由于实时任务有时间限制性的要求，因此为了防止系统出错而导致的任务失败，在实时任务调度算法中还必须考虑容错问题。
