Networked Nonlinear Remote Control for Microreactor Process Using a Distributed Control System Device and Particle Filters

In recent years, microreactors have attracted increasing attention as next-generation chemical reactors, enabling rapid and highly efficient reactions, while requiring precise control against temperature variations. In this paper, a research platform for a microreactor process close to practical implementation is constructed using a distributed control system (DCS) and wireless communication. By establishing such a research platform, not only the effectiveness of control methods but also discussions on system configuration, including operation and maintenance, can be verified and optimized at an early stage. Moreover, operator-based multi-dimensional nonlinear control strategies have been applied in existing studies of channel temperature control. In contrast, this paper extends such strategies by integrating an operator-based feedback scheme with state estimation via particle filters, which simultaneously accounts for unknown communication delay compensation and the nonlinear characteristics of microreactors. Finally, the feasibility and effectiveness of the proposed research platform are verified through real-world experiments.
