1. A digital control system, comprising:

  • a plurality of computing units comprising;

    a plurality of redundant processing units, each of the processing units configured to generate one or more redundant control commands;

    one or more internal monitors for detecting one or more data errors in the control commands; and

    one or more recovery triggers for initiating rapid recovery of a processing unit if one or more data errors are detected;

    a plurality of actuator control units each in operative communication with the redundant processing units, each of the actuator control units having a pair of redundant computational lanes configured to analyze the control commands and provide feedback to the processing units, the actuator control units configured to initiate a rapid recovery if one or more data errors is detected in one or more of the processing units;

    a plurality of smart actuators each in operative communication with a separate one of the actuator control units, the smart actuators configured to receive an actuator control command from the actuator control units and provide feedback to the actuator control units; and

    a plurality of redundant sensor sets in operative communication with the computing units.
