Definition

A weighting factor in the optimal control performance index that balances the collision probability term against the fuel consumption term. A larger coefficient prioritizes safety, requiring more fuel to reduce collision probability; a smaller coefficient prioritizes fuel savings.

Application Value

为航天器的精确控制提供理论依据，确保任务执行的可靠性 该概念为地月空间任务设计提供了重要的理论基础 在实际工程中可用于轨道设计、任务规划或控制系统分析。
