Abstract
A control system and a method of operating the same are introduced that globally optimize associated processes within a process facility. The control system includes a global controller, a bridge predictor and many local controllers. The global controller monitors characteristics of the associated processes and generates, in response thereto, control data for optimizing the process facility. The bridge predictor modifies at least a portion of the control data in response to relationships among the associated processes. The local controllers monitor the associated processes and operate in accordance with the control data to varying degrees to control the monitored associated processes, thereby cooperating with the global controller to optimize the process facility.
Claims33
A control system for controlling associated processes within a process facility, comprising:
- a global controller that monitors said associated processes and generates, in response thereto, control data for optimizing said process facility;
- a bridge predictor using a time-based prediction optimizer that is capable of modifying at least a portion of said control data in response to relationships among said associated processes;
- and
- local controllers that operate in accordance with said control data to varying degrees to control said associated processes, cooperate with said global controller to optimize said process facility and modify said time-based prediction optimizer to correct mis-predictions thereby.
