Abstract: A method and apparatus for controlling movement of a component in a system by a plurality of actuators. An operation actuation command to move the component is received. For each of the plurality of actuators, the operation actuation command is used to generate a feed-forward equalization command for the actuator, the feed-forward equalization command for the actuator is combined with the operation actuation command to provide an equalized actuation command for the actuator, and the actuator is controlled to move the component using the equalized actuation command for the actuator.

Abstract: A system and methods for actuator fatigue monitoring is disclosed. At least two measured actuator forces are received from at least two actuators respectively, and a hybrid force is calculated. The hybrid force is calculated based on a force fight of the at least two actuators calculated based on the at least two measured actuator forces, and a monitored actuator force among the at least two measured actuator forces. An air load of the at least two actuators is estimated based on the at least two measured actuator forces, and a fatigue anomaly is determined based on the hybrid force and the air load.

Abstract: A method is provided to reduce delay in signal processing of a digital control system. The method includes receiving outputs from a digital controller at a first frequency. A pre-load data value is then loaded into an accumulator register and output to a digital to analog converter (DAC). In one preferred embodiment, the pre-load data value is the value of the current digital controller output. In another preferred embodiment, the pre-load data value is the value of a previous digital controller output. The method additionally includes computing a step increment value that includes the difference between the most recent value output from the digital controller and the value output by the digital controller just prior to the most recent value. The step increment value is added to the pre-load data value in the accumulator register to create an augmented value, which is then output to the DAC.
