摘　　要：针对解析塔工业控制中存在的输入输出约束问题,设计一种基于二次插值法的约束预测控制算法.该算法结合阶梯式动态矩阵控制使矩阵运算转化为数值运算,通过引入二次插值法在约束区间内确定满足约束条件的控制增量最优解,从而得到预测控制量.经现场实测模型仿真验证,结果表明该算法是有效的.To ameliorate input and output constraint problems that exist during the control process of an analytic tower, a type of constrained predictive control algorithm is proposed on the basis of quadratic interpolation. By combining the step dynamic matrix control, the algorithm can change a matrix operation into a numerical value operation. The algorithm ensures incremental optimal solutions that satisfy constraint conditions in the con- straint interval by introducing quadratic interpolation to obtain the predictive control value. The results of a field t model simulation show the effectiveness of this algorithm
