| 摘 要： | 传统的预测函数控制通常采用一阶的预测模型，该预测模型不能完全表征被控对象，因此使得传统的预测函数控制的鲁棒性受到一定限制．特征模型是一种比动力学模型简单，但能表征被控对象特征的模型．该文针对预测函数控制算法的缺陷，提出利用二阶特征模型来构成预测模型．通过工程建模获取了被控对象的特征模型，实现了基于特征模型的新型预测函数控制，并通过与采用一阶预测模型的预测函数控制进行比较．理论分析与实验结果均表明，采用特征模型的预测函数控制具有比一阶预测模型更好的控制效果，该算法在SUPCON-JX300X集散控制系统上实现．

| Abstract: | The traditional predictive functional control usually uses first-order predictive model, which does not fully express the plant, therefore is not robust. The characteristic model is simpler than dynamics model and can fully express the plant. Aimed at predictive functional control, this paper uses a second order characteristic model for predictive model that is easily achieved by projection method. Theoretical analysis and experiments show that the new control strategy can provide better results compared with the traditional predictive functional control. The control strategy can be directly applied to the SUPCON-JX300X system. |
