| 中文摘要 |
| 对连铸过程的二冷水控制问题进行了讨论；降而为凝固温度场的边界控制问题，用线性化方法将原问题等价地转化为在几个Randon测度空间求最优测度的有限维线性优化问题，从而得到全局最优控制律。数值试验显示此方法是有效的。 |
| 英文摘要 |
| In this paper,a cooling water control problem in the process of continuous casting of steel is discussed;the boundary control problem of 2-dimensional solidification temperature field is modified into one consisting of the minimization of a linear from over a set of positive measures satisfying linear constraints.The minimization in the new problem is global and can be approximated by a finite-dimensional linear programming problem.A nearly optimal control is constructed.A simulation is given to illustrate the procedure. |
