Applied research on main steam temperature control based on internal model control

摘要

Principles and characteristics of internal model control (IMC) are illustrated. It has a simple and general structure such as that of a PID controller. Applications of IMC based on single loop PID controller tuning in main steam temperature of boiler in power plant were investigated. It can also become easier to achieve in a distributed control system (DCS) via control module configuration. It was applied in boiler of power plant to tune the main steam temperature PID parameters. The application results demonstrate the validity of the proposed method.
