Matlab遗传算法求解多组分系统泡点问题

Solution to the Bubble Point of Mixture with Genetic Algorithm of Matlab

使用Matlab语言对乙烯(20%)、乙烷(30%)、异丁烷(25%)和正丁烷(25%)四元混合体系建立泡点计算模型、适应度函数和非线性约束条件,并用遗传算法进行求解。获得泡点温度为255.2K,5个目标值误差之和仅为0.033%,能够满足工程应用要求。

Creating mathematical model of bubble point,fitness function and nonlinear constraints were established for quaternary mixtures of ethylene（20%）,ethane（30%）,isobutane（25%） and butane（25%） using matlab,then solving by genetic algorithm.The result was that total error of 5 targets was 0.033% and the temperature was 255.2 K,which can meet the engineering requirements.
