摘要
基于都江堰灌区柏条河三孔平板闸门运行情况,运用水力学公式及经验公式,得到了闸门流量与开度的数学模型,进而采用Matlab的Simulink平台建立了单孔闸门流量—开度仿真模型,在此基础上利用Simulink内置模块及根据实际情况编写的M函数,建立了基于闸门启闭规则的三孔闸门流量—开度仿真模型,该模型可根据所需流量计算出各闸门对应开度,经验证模型仿真结果与理论值相符合。
Based on the operation ot three-hole flat-slab gate ot tsaltlaohe in Du31angyan Irrigation olstrtct, tne nyuraulies and empirical formula are used to deduce the mathematical model of gate flow-opening. And we establish the simulation model of flow-opening for a single-hole gate by using Matlab/Simulink. Based on the regulation of gate opening, three-hole opening-flow simulation model is established by using inner modulus in Matlab/Simulink and compiling M-function. This model can calculate the corresponding gate opening in terms of the required flow. Finally, it is proved that the result of the simulation model accords with the theoretical value.
