本文分析一类具有Size结构的竞争种群系统的最优输入率控制问题.首先利用特征线法给出解对控制变量的连续依赖性定理,又利用共轭系统和Ekeland变分原理证明最优控制的存在唯一性,并借助于法锥概念得到最优控制的必要性条件.
In this paper,the optimal control problem for inputting rate of a Size-structure competing system is studied. At the beginning, the continuous dependence of solution on control variable is given using characteristic method. Then by the adjoint system and the Ekeland variational principle, the existence and uniqueness of the optimal control are obtained. By the conception of normal cone, the necessary conditions of the optimal control are given.
