Abstract: With catalysis system, carbonylation of methanol liquid is a better method in manufacture of acetic acid. However previous control mode can not well meet technique demands. This paper made some modification on reaction process control based on manufacturing technique. Aimed at much influence upon temperature including uncertainty, cross coupling effects and big delay about model, predictive functional control (PFC) technique combined with PID and feedforward are applied to temperature control of reaction process through supervisory total distributed control which leads to the improvement of regulatory capacity for both reference input tracking and load disturbance rejection. Practical results show stable and reliable system operation.

Abstract: How to master the technology innovation and method and technique in product exploitation, has been always one of the issues of research and discussion. Based on more than 40 years’ experiences of engagement in mechanical and electrical technology on product research, design, teaching, the author proposed and constructed "OF + N" theoretical method (for short: method of creating inventive and innovative topics) suitable for technological innovation and product development. Some innovative design was implemented using the theoretical method through years of research and probe.
