摘要
对典型泵站系统的部分明渠段的小扰动工况进行了研究,建立了多级泵站组成的引水系统,包括管道、明渠以及泵站进出水池的传递函数形式的数学模型。用线性最优控制系统设计程序求解控制器参数,并用状态空间法求解小扰动情况下的过渡过程。其中对选取不同状态量权重因子的最优控制系统及PID调节器控制的系统分别进行了仿真计算,得出了一些启示性的看法。
The small-disturbed working conditions of part open channel of typical pump station system has been studied to establish the water diversion system composed by multi-pumping stations, including the mathematic model of pipeline, open channel and inlet and outlet pools of pump station. The design program of optimal control system was used to solve the parameters of controller and the condition spatial method to solve the transient process under the condition of small disturbance. The simulation calculations were respectively made for the optimum control system and PID governor controlling system and some results have been gained.
