造纸机不同时滞多变量自校正控制器
A Multivariable Self-Tuning Controller for Paper Machine with Unequal Time Lag
-
摘要: 本文针对造纸机的纸张定量及水分,研制了具有不同时滞的多变量自校正控制器,增加了 积分器和前馈补偿,用增广最小二乘法估计全部参数,实际运行获得满意的控制效果;还介绍 了微机控制系统的构成及自校正控制系统的调试经验.Abstract: In order to control the basis weight and moisture in a paper-making process, a new multivariable self-tuning controller with unequal time lag is presented in this paper. Integrators and feedforward compensators are added to the self-tuning controller, and all parameters are estimated by the Extended Least Square method. Based upon the satisfactory control results in a paper mill, some practical problems on the design of a microcomputer control system and the adjustment of the self-tuning controller are discussed.
