摘要
逐次 2次规划法 (SQP)是目前求解非线性约束问题十分有效的方法 ,但一般都采用罚函数进行线性搜索 ,这使得它有了很大的限制性 ,RogerFletcher和SvenLeyffer等提出了一种filterSQP优化方法 ,在充分研究这种方法的基础上 ,编制了计算程序 ,将其应用到化工过程优化中 ,多种计算实例表明 。
Sequential Quadratic Programming(SQP)is the most efficient algorithm for nonlinear optimization.But it generally uses a penalty function to perform linear search,so it has prodigious limitation.A new SQP method has been developed at the University of Dundee(Roger Fletcher and Sven Leyffer,1997),which avoids using a penalty parameter to weight the constraints and objective.On the basis of the sufficient research to this kind of algorithm,the computer programme was written and applicated to the optimization of chemical process .The results of numerical calculated example showed that the new method surpassed the tranditional SQP algorithm.
