摘　　要：针对工业生产中的复杂非线性模型,以中板轧制为例,提出了一种实时控制中复杂非线性问题的简化处理方法,由出口参数求解入口参数。主要思想是避免求解反函数的过程,只利用原模型,从初始工作点出发,用二次曲线进行拟合,经过若干次迭代过程,得到所需结果。该方法在实际应用中获得了很好的效果。Aiming at the complicated nonlinear models in plate rolling, a simplified arithmetic for nonlinear model in real time control to find the to solve the inverse tunction, but to use quadra input from the output was put forward. The main idea is not tic fit method to approach the intrinsic model through some initial points. Finally, the expected result was obtained after several iterations. The simplified arithmetic has been used in actual application with good result.
