The principle of MPC is to have a process model, which is able to predict the process response, in the MPC controller. The manipulated variable is tuned in order to minimize the deviation between the set point and the predicted response for a period of time in the feature. The goal of process control can therefore be achieved by regulating the manipulated variable. We use neural networks, which have strong ability of identification. Then we collocate with optimal operation to establish a neural network predictive control (NNPC) structure. On the other hand, in order to reduce the error between the predictive model and the true system immediately and to increase the accuracy of prediction, we use the dynamic backpropagation (DBP) learning algorithm to adjust the weights of neural network during the on-line procedure. The whole control structure becomes an adaptive neural network predictive control (ANNPC). We also use this kind of control method to control distributed parameter chemical processes systems. Through the simulation, we get the performance and tenacity of this control methods. weiwu 吳煒 2006 學位論文 ; thesis 61 zh-TW
