摘要

神经网络在过程控制的一般领域有着广阔的应用前景。本文主要研究了将反向传播网络应用于基于优化的模型预测控制方案。由于可以导出神经网络模型的梯度和Hessian的解析表达式,并且这些表达式可以并行计算,因此可以实现极快的计算速度。以pH CSTR为例说明了控制方法。

Optimizing Neural Net based Predictive Control
Neural networks hold great promise for application in the general area of process control. This paper focuses on using a backpropagation network in an optimization based model predictive control scheme. Since analytical expressions for the gradient and Hessian of the neural net model can be derived and these expressions can be calculated in paralle, extremely fast computation times are possible. The control approach is illustrated on a pH CSTR example.
