  • Patent number: 11016453
    Abstract: Exemplary embodiments described in this disclosure can pertain to a controller apparatus that provides control signals to a power generation unit. The controller apparatus can include a first controller, a second controller, and a supervisor that can place the first controller in an in-service state and the second controller in a standby state. The first controller provides control signals to the power generation unit when in the in-service state. The second controller can include a copy of an application program contained in the first controller. This copy of the application program can be modified or replaced while the second controller is in the standby state. The supervisor may then opt to place the second controller in the in-service state and place the first controller in the standby state. The switch-over of controllers is carried out in a substantially simultaneous manner that eliminates interruption in control operations.
