1. A multivariable control method for controlling a process, the process being characterized by a first set of process variables and a first set of controlled objectives, comprising the steps of:

  • operating the process at an initial set of process variables and an initial set of controlled objectives;

    monitoring the first set of process variables and the first set of controlled objectives while continuously operating the process;

    monitoring an effect that changes in the first set of process variables have on the first set of controlled objectives, wherein a monitored set of process variables is generated from the changes in the first set of process variables, and a monitored set of controlled objectives is generated from the effect that changes in the first set of variables have on the first set of controlled objectives; and

    adjusting one or more members of the monitored set of process variables based upon a non-linear optimization with respect to a desired set of controlled objectives, utilizing the monitored set of process variables and the monitored set of controlled objectives in the non-linear optimization, wherein said adjusting one or more members of the monitored set of process variables includes changing at least one of the members of the monitored set of process variables, and the monitored set is a modified version of the initial set of process variables input to a device.
