METHOD OF TUNING A PROCESS CONTROLLER

摘要

An model predictive control (MPC) type process controller(31) already implemented in the process control layer of the automation system is utilized in automatic determining initial values of MPC tuning parameters. The MPC controller (31) can be switched between an online process control mode (A) and an offline MPC tuning mode(B). In the online process control mode (A) the MPC controller (31) performs an online process control task in a real-time operating system environment on a process control layer of a process automation system. In the offline MPC tuning mode (B), the MPC controller is operated in the real-time operating system environment on the process control layer of the process automation system under control of an optimizer unit (33) to determine MPC tuning parameters meeting a predetermined quality criterion.
