Intelligent Control Based on System Output Distribution

According to system output distributions, characteristic variables are proposed. Based on this information, a intelligent control system is presented. Simulation results are satisfactory. Experiments are carried out in a pilot binary distillation column (15 trays with feed of alcohol and water mixture) controlled by a microcomputer system. It is shown that the control strategy succeeded and has significant advantage compared with a conventional control strategy in nonlinear distributed parameter systems.
