Davison's robust, multivariable, feedback-feedforward controller (DAVISON, E.J. : IEEE Trans., 1976, AC-21, pp. 35-47) is applied to the control of a pilot-scale binary distillation column, as a master loop in a cascaded configuration. The inner or slave loop consists of the original plant with multiloop proportional control. This cascaded configuration is shown to have a number of advantages for practical implementation. The performance of the controller is evaluated by experimental application to a computer-controlled distillation column. The robust controller gives improved control performance compared to that achieved using conventional multiloop proportional plus integral plus derivative (PID) control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
