DESIGN AND EXPERIMENTAL EVALUATION OF ROBUST PID AND PI-PD TEMPERATURE CONTROLLERS FOR HEAT PUMP DRYER
This paper presents both PID and PI-PD temperature controller design approaches using deoxyribonucleic-acid-algorithm (DNA),and investigates their applications to temperature control for heat pump dryer systems.A PID controller with desired control performance index is off-line designed using DNA computing method,in order to achieve the minimum of a performance index,named integrated squared error (ISE) or the integral of time multiplied by square of the error (ITAE).With the obtained threeterm parameters of the designed PID controller,a PI-PD controller is then constructed in order to control more general industrial processes or plants.Computer simulations are performed to illustrate the superior performance and merit of the proposed PID and PI-PD controllers in comparison with conventional ones.The applicability and usefulness of the proposed control scheme are well exemplified by conducting experiments on a heat pump dryer.Both simulations and experimental results reveal that the proposed PID and PI-PD controllers outperform the conventional ones.
