研究了一类非线性种群系统的最优控制问题.利用Ekeland变分原理和共轭系统证明了最优收获的存在性,并借助于法锥概念得到了最优控制的必要性条件.
We investigate the optimal control problem for a nonlinear age-dependent population system.The existence of the optimal control is proven by using Ekeland’s variational principle and adjoint system,we also obtain the necessary condition of optimality by means of the concept of the normal cone.
