F. Alsunni et T. Alnemer, A SMITH PREDICTOR FL-BASED CONTROLLER FOR PROCESSES WITH LONG DEAD-TIME, International Journal of Systems Science, 28(12), 1997, pp. 1251-1258
A Smith predictor (SP) fuzzy logic (FL) based controller for processes
with long dead time is proposed. The basic concept is to combine the
Smith predictor scheme with FL. The FL, in this scheme, is going to be
used to auto-tune the PI controller while the SP is going to compensa
te for the long dead time that is commonly associated with different p
rocesses. The new scheme has been tested on several simulated plant mo
dels and demonstrated marked improvements in the performance. The simu
lation results demonstrated the ability of the new scheme to accommoda
te uncertainties in the plant model.
