摘　　要：定量和水分是造纸过程中影响成纸质量的两个重要因素。针对其中存在的强耦合特性,提出了一种基于无穷时域状态空间模型的预测控制算法。该控制器具有结构简单、可调参数少以及方便调节的优点。仿真结果表明,无穷时域预测控制不仅能解除定量和水分之间的耦合关系,还对量测噪声具有很强的鲁棒性,是一种提高定量和水分控制效果的有效方法。Basis weight and moisture content are two important factors of paper quality in papermaking process. Aiming at the characteristic of strong coupling, the predictive control algorithm based on infinite horizon state space model is presented. Advantages of this controller are simple structure, few tuning parameters and easily tuning method. Simulation results indicate that besides the feature of the decoupling between basis weight and moisture content, the infinite horizon predictive control has strong robustness with respect to measurement noise. It is proved that this control approach is effective for improving the performance of the basis weight and moisture content control system.
