Neural network predictive control of a heat exchanger
Possibility to use a neural network predictive control (NNPC) strategy for control of a heat exchanger is studied. The heat exchanger is a tubular one and it is used for preheating of petroleum by hot water. The control objective is to keep the output temperature of the heated stream at a desired value and minimize the energy consumption. The advantage of the NNPC is that it is not a linear-mod...
متن کاملNeural Network Control of a Heat Exchanger Pilot Plant
In this paper, a neural network based predictive controller is designed to govern the dynamics of a heat exchanger pilot plant. Heat exchanger is a highly nonlinear process; therefore, a nonlinear prediction method can be a better match in a predictive control strategy. Advantages of neural networks for the process modeling are studied and a neural network based predictor is designed, trained a...
متن کاملMultivariable Optimal Control of a Heat Exchanger Network with Bypasses
Heat exchanger networks present an interesting control problem due to coupling among process streams. In this work, the linear quadratic regulator (LQR), a feedback optimal control technique, is used to control stream temperatures on a laboratory scale heat exchanger network, through bypass manipulation, in a multivariable system. The LQR design was based on a mathematical model of the plant an...
متن کاملFuzzy Model-based Neural Network Predictive Control of a Heat Exchanger
The paper investigates a predictive control algorithm to regulate the output petroleum temperature of the tubular heat exchanger. In the controller design, a Takagi–Sugeno fuzzy model is applied in combination with the model predictive control algorithm. The process model in form of the Takagi–Sugeno fuzzy model is obtained via subtractive clustering from the plant's data set. The neural networ...
متن کاملControl of a Heat Exchanger Using Neural Network Predictive Controller and Auxiliary Fuzzy Controller
The paper presents an advanced control strategy that uses the neural network predictive controller and the fuzzy controller in the complex control structure with an auxiliary control variable. The controlled tubular heat exchanger was used for pre-heating of petroleum by hot water. The heat exchanger was modelled as a nonlinear system with interval parametric uncertainty. The set point tracking...
