Abstract
Heat exchangers are important pieces of equipment to transfer heat between process fluid media. In some processes the working fluid temperatures must be exactly controlled. The common control method such as PID feedback control might not provide high control quality because such a control is based on the deviation between inputs and outputs, and therefore the disturbances in the outputs cannot be eliminated if disturbances in the inputs occur. To overcome the disadvantages of traditional control methods, a model predictive control method is developed. A mathematical model for dynamic behaviour of one-dimensional flow multistream plate-fin heat exchangers is proposed to calculate the adjustment parameters. A model
