摘要:: 本文讨论了造纸过程自校正拉制系统的设计与仿真，其一是把文［１］的ＳＩＳＯ系统自校正前馈控制器与文［３］的多变量广义最小方差自校正解耦控制器结合起来根据造纸过程的动态特性，提出了一种基于输出预报的新的自校正前馈补偿解耦控制器（ＳＴＦＣＤＣ）。仿真结果表明，这种控制器对ＭＩＳＯ系统仍具备文［１］的特点，其二是对控制器参数辨识方法进行了有效的改进，提出了一种实用的递推增广最小二乘算法（ＰＲＥＩＳ算法），仿真结果表明，该算法收敛速度较文［１］快，而且克服了常规ＲＥＩＳ算法中Ｐ（Ｋ）阵出现负定的情况。

Abstract:: This article discusses the design and simulation of the self -correction of the papermaking process. One is to combine the SISO system self -correction of the SISO system [1] of the text [1]. To. The simulation results show that this controller still has the characteristics of [1] in the MISO system. The second is to effectively improve the controller parameter recognition method, and propose a practical reciprocity to increase the smallest minimum secondary algorithm (PREIS algorithm). In the algorithm, the P (K) array is negative.
