试图用最优控制理论来描述水库调度的连续变化特性，建立了水库调度的最优控制模型，用最大值 原理给出了水库调度最优控制的必要条件，分析了不同条件和环境下水库调度最优控制策略和具体表示形式。 最后对某具体算例进行了分析，结果表明该方法是有效的。

This paper tries to describe the continuous transformation characteristic of reservoir operations with optimal control theory. After constructing the optimal control model of reservoir o perations, the paper presents the necessary condition of optimal control of reservoir operations using maximum principle and analyzes the characteristic and concrete expression of optimal control strategy of reservoir operations in different conditions and environment. At last, an analysis of a numerical example is presented and the results indicate the approach is valid.
