Abstract: |
Heat exchangers are devices whose
primary responsibility is the transfer (exchange) of heat, typically from one
fluid to another. However, they are not only used in heating applications,
such as space heaters, but are also used in cooling applications, such as
refrigerators and air conditioners. Heat exchange processes often contain
time-delay. This paper deals with design of universal and robust digital
control algorithms for control of great deal of processes with time-delay. These algorithms are realized by the digital Smith Predictor (SP)
based on polynomial approach – by minimization of the Linear Quadratic (LQ) criterion.
For a minimization of the LQ criterion is used spectral factorization with
application of the MATLAB polynomial Toolbox. The designed polynomial digital
Smith Predictors were verified in simulation conditions. Simulation model for
a verification of the designed control algorithms was realized using
experimental measured data on the laboratory heat exchanger. The program
system MATLAB/SIMULINK was used for simulation of the designed algorithms. |
