1. 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; and
local controllers having a dynamic prediction task and a local linear program/quadratic program optimization task, said local controllers operating in accordance with said control data to varying degrees to predict, optimize and control said associated processes and thereby cooperate with said global controller to optimize said process facility.

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 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 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.
