实验一:三次样条插值(P56,例6)
一、实验目的:
1) 掌握三次样条插值的运用
2) 了解拉格朗日插值在高次上的误差
二、实验环境:Matlab6.5
三、实验内容:
1) 给定函数f(x)=1/(1+x2),-5<=x<=5,节点xk=-5+k,(k=0,1,2…10),用三次样条插值求S10(x),S10’(-5)=f’(-5),S10’(5)=f’(5)。
2)作原函数f(x),拉格朗日插值函数Ln(x),三次样条差值函数Sn(x)。画出三个函数的图像,比较它们的区别。
(Experiment I: cubic spline interpolation (P56, cases of 6) First, the experiment was: 1) cubic spline interpolation to master the use of 2) understanding of Lagrange interpolation in high-error second, experimental environment: Matlab6 .5 c, experimental elements: 1) a given function f (x) = 1/(1+ x2),-5 <= x <= 5, node xk =- 5+ k, (k = 0,1,2 ... 10), using cubic spline interpolation for S10 (x), S10 (-5) = f (-5), S10 (5) = f (5). 2) for the original function f (x), the Lagrange interpolation function Ln (x), cubic spline difference function Sn (x). Draw the three functions of images, compare the difference between them.)

DMC
DMC的主要特征是预测模型采用阶跃响应特性建模 设计过程中固定格式:用二次型目标函数决定
控制量最优值增量序列 自校正动态矩阵控制等多种算法 参数调整:用改变二次型目标函数中的权系数
阵来实现.(With the research of dynamic characteristic of electrical resistance furnace and the imp rovements of
MPC in detail, the effects between DMC and P ID in the temperature control system of electrical resistance furnace
was compared. The results confirmed that DMC not only overcomes the inaccuracy of the models and the
variability of the parameters, but also achieves better performance index than P ID in accordance with the
expectation of given curve.)
