Exemplary embodiments described in this disclosure pertain to a system that includes a high-level controller coupled to a low-level controller in an arrangement that allows the high-level controller to cooperate with the low-level controller for controlling a power generation unit. The high-level controller generates supplementary signals and/or supplementary code that is provided to a surrogate controller. The surrogate controller uses the supplementary signals and/or supplementary code to generate control software that is provided to the low-level controller for controlling certain operational aspects of the power generation unit that cannot be independently controlled by the low-level controller. If the high-level controller is placed in an independent mode of operation for any reason, the surrogate controller continues to cooperate with the low-level controller for controlling various operations of the power generation unit that were being controlled by the low-level controller prior to the high-level controller entering the independent mode of operation.
