摘要
本文利用热传导方程中参数识别方法,将电渣重熔过程中两相区的识别问题化为最优控制问题来解决。根据脉冲变分原理,给出了识别参数的梯度公式及计算方法,最后的仿真结果说明了该方法的可行性。
In this paper, a new method to determine the Interface of molten metal and ingot in an electro-slag remelting process (ESR) is presented. This method is based on the principle of pulse variation given by References [1, 2]. And the identification problem is transferred into an optimal control problem. Examples are given to show the efficiency and feasibility of this method.
