Abstract

It is extremely significant to precisely control exit temperature of heat exchanger in industrial production. However, traditional control strategy has a great deficiency to be applied to temperature control system which is nonlinear, large inertia, pure delay and variant parameters. Smith predictor (SP) provides an effective method to compensate for time delays, but it might make the system unstable out of mismatch of identification model. Dynamic matrix control (DMC) can improve system performance by multiple steps prediction and online rolling optimization on the basis of feedback correction. This paper compares and analyzes the advantages and disadvantages of the above two algorithms by the means of modeling and simulation.
