ABSTRACT:
A two-stage model predictive control (MPC) controller uses a process model and two separate MPC control modules, including a feedforward MPC control module and a feedback MPC control module, to determine a set of control signals for use in controlling a process. The feedforward MPC control module uses the process model to determine a feedforward control component for each of a set of control signals and the feedback MPC control module uses the process model and one or more measured process outputs to determine a feedback control component for each of the set of control signals. The two-stage MPC controller combines the feedforward control components with the feedback control components to form the final control signals used to control the process. The two different control modules may receive separate and different inputs from the process to determine the feedforward control components and the feedback control components, and may be tuned separately, to thereby enable a control operator or other user to perform more standardized and stabilized tuning within an MPC controller environment.
