摘要
采用面向结构图的仿真方法,基于Matlab/Simulink软件平台,提出了分汊河道截流过程仿真与优化方法。结合截流情况建立截流系统仿真模型,并采用混合遗传算法对模型进行求解,在仿真基础上对截流系统进行优化分析。该方法实现了建模与仿真的模块化、结构化和可视化,并且模块可重用性强便于模型的修改和集成。面向工程实例,根据河道汊口处两江水位相等的特征,建立了目标函数方程并采用混合遗传算法求解,该算法求解精度高、收敛速度快,仿真结果证明了以上方法的科学性和有效性。
The structural drawing-oriented simulation method is used to simulate and optimize the closure of a crotched river. On the platform of software Matlab/Simulink the model for simulation is established. The hybrid genetic algorithm is applied to solve the model and on the basis of simulation model the optimization of the closure system is carried out. By using this proposed method the modularization, structuralization and visualization of the whole closure process can be realized. An example by using maintaining the equality of water levels in both sides of crotched fiver as the objective function verifies the effectiveness of this method.
