Practice and Challenges in Chemical Process Control Applications in Japan

Abstract

This paper surveys how the three central pillars of process control – PID control, conventional advanced control, and model predictive control – have been used and how they have contributed to production activity from the viewpoint of the process control section in the Japanese chemical industry. In addition to introducing practical methods and their application results, the authors point out challenging problems, which include the development of a general model-based control technique to enhance batch process control.
