摘要:

该文研究一类带有弱连续算子的发展方程的一个最优控制问题. 通过运用Rothe方法和弱连续算子的一个满射定理, 建立方程的可解性. 然后证明最优控制问题的最优状态-控制对的存在性. 最后把主要结果应用到非平稳的Navier-Stokes-Voigt方程上.

关键词: 发展方程, 最优控制, 弱连续算子, Navier-Stokes-Voigt方程

Abstract:

In the paper we study an optimal control problem for a class of nonlinear evolutionary matrixs involving weakly continuous operators. By exploiting the Rothe method and using a surjectivity result for weakly continuous operators, we establish the solvability for the matrix. Then we show the existence of optimal state-control pairs for the optimal control problem. The main results are applied to non-stationary Navier-Stokes-Voigt matrix.

Key words: Evolutionary matrix, Optimal control, Weakly continuous operator, Navier-Stokes-Voigt matrix
