ScholarBank@NUS Repository. | Abstract: | In this paper, the development of relay-enhanced multi-loop PI controllers is described for multivariable processes. The control system employs a relay in series with the controller. The relay can ensure a satisfactory level of closed-loop performance and it also yields oscillations for tuning of the PI controller based on an equivalent process model for each loop. A simulation example [on a two-inputs-two-outputs (TITO) process] is provided to illustrate the effectiveness of the proposed method and to compare its performance to an existing method. © 2003 ISA - The Instrumentation, Systems, and Automation Society. | Source Title: | ISA Transactions | URI: | http://scholarbank.nus.edu.sg/handle/10635/57243 | ISSN: | 00190578 |
