1. A method of controlling load on a machine using a controller comprising:

  • determining at least one of a process variable associated with the machine and a control output associated with the process variable using an iterative process, wherein a value of the process variable is received from a sensor and wherein the control output is output from the controller;

    determining a maximum value of the process variable using a predictive model of the machine while holding the control output substantially constant over a prediction period; and

    incrementing the control output of the controller if the determined maximum value of the process variable is within an allowable limit range; and

    setting the control output of the controller to a last value of the control output determined that did not cause the process value to exceed the allowable range.
