1. A computer-implemented method for implementing an indirect controller with a system model in a plant operable for performing a process, the plant having a plurality of inputs, the inputs being manipulable by a controller to operate the plant, a particular combination of inputs received by the plant defining an operating region, comprising:

  • using the indirect controller to operate the plant;

    detecting that the performance of the system model is low;

    using a direct controller to operate the plant by maintaining operation around a particular operating region corresponding to detecting that the performance of the system model is low;

    adapting the system model;

    detecting that the performance of the system model is acceptable; and

    selecting the indirect controller to operate the plant.
