Abstract:

Systems and methods are provided for effecting control through multi-stage voting. A control system may be in communication with an actuator device responsive to a voted command. A multi-stage voting system may be configured to determine the voted command. A set of controllers and a monitor controller may provide commands to the multi-stage voting system. The multi-stage voting system includes logic with a first stage that compares the commands of the set of controllers to each other, and a second stage that compares at least one of those commands to the monitor command. The multi-stage voting system delivers the voted command to the actuator device based on the comparisons made in the first and second stages. The actuator device effects an operation in response to the voted command.
