PROPOSED METHOD SCOPE OBJECTIVE • TAKING INTO ACOUNT THE LATEST TECHNOLOGIES IN THE MIMO SYSTEMS. • INCLUDES NUMEROUS CASE STUDIES, WORKED EXAMPLES, WHICH IS COMMON USE IN PROCESS INDUSTRY. • FOCUSES ON THE THEORY AND APPLICATION ASPECTS OF MULTIPLE INPUT, MULTIPLE OUTPUT (MIMO) CONTROL SYSTEMS. MODEL BASED ANALYTICAL DESIGN OF MULTI-LOOP CONTROL SYSTEMS • PRESENTS CURRENT ISSUES ON MIMO SYSTEMS. • DEVELOPS NEW MULTI-LOOP PID/PI CONTROLLERS FOR MULTIVARIABLE PROCESSES. • WEIGHTED SUM Mp CRITERION FOR MULTI-LOOP CONTROLLER TUNING Closed-loop responses to sequential step changes in set-point for WB column. Optimum solution map of WB column. • Ms CRITERION FOR THE MULTI-LOOP CONTROL SYSTEM Closed-loop response to sequential step changes in set-point for OR column. Effects of Mslow on the IAE: OR column. Conclusions In this researches, we proposed an efficient method of designing multi-loop PID controllers. The weighted sum Mp criterion was introduced as performance measure to cope with both performance and robustness in multi-loop systems. For a same reason, Ms criterion also can be implemented easily in decentralized control systems. The simulation results show that the proposed method is very effective both set-point tracking and disturbance rejection . Closed-loop response to sequential step changes in disturbance for OR column. Homepage : http://psdc.yu.ac.kr TEL : +82 053)810-3241 E-mail : mynlee@yu.ac.kr
