摘要
具体着眼于水锤源的主动控制,提出了应用动态规划算法进行输水系统限压条件下瞬态阀调节最优控制策略决策的基本理论和具体方法。研究揭示了限压阀调节最优策略和水锤波动机理之间的内在联系,进一步丰富了用阀调节的手段对输水系统水锤发生源乃至全过程进行有效控制的理论体系。
Based on the active control of the source of water hammers,this paper proposes the basic theory and the method of using the dynamic programming algorithm to obtain the optimal strategy decision under the condition of the pressure limiting valve-stroking in the conveyance system.The study reveals the internal relations between the optimal strategy decision of the pressure limiting valve-stroking and the mechanism of fluctuations in water hammers.Besides,it enriches the theoretical system of means to effectively control the source of water hammers in the whole process of water conveyance systems.
