我们研究由半线性反应-扩散方程组支配的最优控制问题。对支配系统的假设条件进行了设定,使得我们的结果适用于多种模型,包括Brusselator、Schnakenberg和Gray-Scott系统。我们在不对数据施加任何非负性假设的情况下,证明了支配系统解的存在性和唯一性。这使得我们能够研究无约束、控制约束和状态约束的最优控制问题。对于所有这些问题,我们推导了一阶必要和二阶充分最优性条件。控制通过边界作用于激活剂方程。数值算例表明,抑制剂和激活剂都能被有效控制。
英文摘要
We study optimal control problems governed by a system of semilinear reaction-diffusion equations. The assumptions on the governing system are formulated so that our results apply to several models, including the Brusselator, Schnakenberg, and Gray--Scott systems. We prove the existence and uniqueness of a solution to the governing system without imposing any non-negativity assumption on the data. This allows us to study unconstrained, control-constrained, and state-constrained optimal control problems. For all these problems, we derive first-order necessary and second-order sufficient optimality conditions. The control acts on the activator equation through the boundary. Numerical examples demonstrate that both the inhibitor and the activator can be efficiently controlled.
