This Proceedings contains papers presented at the sixth IFAC Symposium on Dynamics and Control of Chemical Processes (DYCOPS 2001), which was held on Jejudo Island, Korea, on June 4-6, 2001. The triennial DYCOPS symposium is one of IFAC's highest-profile regular events, and has established an enviable reputation for quality. The reputation and coverage of DYCOPS ensures that these events always provide a comprehensive showcase of the best and latest research into all aspects of process control. DYCOPS-6 had as its theme "Bridging Engineering with Science," and explored how the process control community should react to wider developments in chemical engineering research, where molecular-level phenomena and product design as related to materials and biotechnology are becoming increasingly important. Featuring papers by many of the world's leading experts in process control, the Proceedings of DYCOPS-6 form an indispensable resource for process control engineers and for chemical engineers seeking to understand the latest developments in chemical process control. Altogether over 100 papers are presented, on topics such as batch process control, model predictive control, control of distillation columns, fault detection, and many others.
