Abstract: A distributed control system may include a main processing unit, a distributed control module, and a controllable component. The distributed control module may be configured to receive a nominal command reference from the main processing unit, determine a series of cumulating command references based at least in part on the nominal command reference; and output a series of cumulating control commands to the controllable component. The series of cumulating control commands may be based at least in part on the series of cumulating command references.

Abstract: A method and system of scheduling a demand for a process inner loop are provided. The loop controller includes an inner loop control system configured to generate a control output signal for a controllable member and a schedule demand module configured to receive parameter values for a controlled variable of a process from a parameter source and to generate a scheduled demand output using a demand schedule. The loop controller also includes a schedule prediction module configured to predict a future value of a scheduling parameter based on a historical performance of the inner loop control system and current system dynamics and to generate a scheduled rate output. The schedule prediction module includes the rate-of-change of a scheduling parameter and a lead time input that defines a look-ahead time period used with the parameter rate signal to determine a future predicted value of the controlled variable.
