Abstract
A system for controlling a plant process wherein the plant is over-actuated with N+1 actuators and provides N performance variables is disclosed. The system includes an outer-loop controller operable to compare N performance variable values from the plant with a reference set point and provide a desired virtual control input to an inner-loop controller. The inner-loop controller receives the desired virtual control input from the outer-loop controller and provides real control inputs to the at least N+1 actuators. The N+1 actuators receive the real control inputs and subsequently provide an actual virtual control input to the plant. Upon receiving the actual virtual control input from the N+1 actuators the plant is operable to produce N updated performance variable values in an optimized manner.
