| 摘 要： | 针对三相生物流化床味精废水处理过程的闭环控制进行研究,在考虑其大滞后性、复杂非线性等特点的基础上,提出一种基于人工神经网络的非线性模型预测控制方法以实现处理过程的闭环优化控制.该方法首先建立味精废水处理工艺模型,采用非线性模型预测控制方法对模型进行校正,并利用序列二次规划法解决其约束非线性规划问题,最终实现味精废水处理的闭环优化控制.仿真和实验结果表明该方法有效,可实现闭环实时控制,具有广阔的应用前景.

| Abstract: | The close-loop control in the MSG wastewater treatment system based on three-phase biological fluidized bed was studied in this paper.A nonlinear model predictive control method based on ANN was established considering the characteristics of large time-delays and complex nonlinearity.First the chemical model of MSG wastewater treatment process was built up.Next the model was modified by using the nonlinear model predictive control method.Then the sequential quadratic programming method was employed to tackl... |
