PROBLEM TO BE SOLVED: To create and use an adaptive DMC type or other MPC controller.;SOLUTION: An embodiment uses a process model to generate an MPC control model, creates an MPC controller algorithm, and downloads it to an MPC controller on the basis of the new control model while the MPC controller is operating on line. This technique, which is generally applicable to single-loop MPC controllers and is particularly effective in MPC controllers with a control horizon of one or two, changes the process model and enables an MPC controller to be adapted during normal operation of a process. The adaptive controller can be easily implemented within a distributed controller of a process control system, while providing the same control as or better control than a PID controller, especially in dead time dominant process loops, and in process loops that are subject to process model mismatch within process time to a steady state.;COPYRIGHT: (C)2014,JPO&INPIT
