Current Activities on Nonlinear MPC and some other Process Control Problems at Mitsubishi

Industrial application examples of nonlinear model predictive control to polyolefin reactors at Mitsubishi Chemical Corp. will be introduced. NMPC has a strong potentiality of improving control of highly nonlinear processes; polyolefin reactor control is one such example, because it has to accomodate various modes of operations such as frequent grade changes, load changes, catalyst changes, etc. Some other issues related to polymerization reactor control will be also discussed.

Biographical Sketch:
Hiroya Seki graduated from Tokyo University, Department of Mechanical Engineering in 1986. He received a Master of Science Degree from the same department in 1988. His master thesis, entitled "Precise control of a flexible manipulator", focused on application of LQ control to positioning and vibration suppression of a flexible robotic manipulator. In 1988, he joined Mitsubishi Chemical Corporation, and has been engaged in research/development and application of advanced control technique to chemical processes and mechanical systems. From 1995 to 1997, he stayed at ETH as a visiting researcher in the group of Prof. Morari and studied nonlinear model predictive control. Currently, he is applying NMPC to polyolefin reactor control.
