Systems and methods for fault toleration actuation include an actuator with a position. A first sensor measures a first parameter associated with the actuator. A second sensor measures a second parameter associated with the actuator. A sensor fusion module receives data from each of the first and second sensor and executes a sensor fusion process on the data received to estimate the position of the actuator. A fault detection module is configured to receive data from the first and second sensor, to receive sensor fusion data from the sensor fusion module, to compare the data received from the first and second sensor with the sensor fusion estimate, to identify an error in the data received from either of the first or second sensor based on the comparison, and to determine a fault exists in the first or second sensor based on the error.

A system and method for testing no-back systems. In one embodiment, the system and method includes multiple actuators that are driven in an asynchronous manner as to impart internal forces that mimic external loads on the system. The actuators can be monitored to determine whether the no-back systems are performing as expected when loads are applied to the actuators.

An actuator control system can include a plurality of electro-mechanical actuators for operating one or more end effectors, a plurality of position sensors associated with the plurality of electro-mechanical actuators, each of the plurality of positions sensors providing an output indicating an actual position value, and a control system. The control system can be configured to receive an activation command signal and the position sensor outputs, and send a speed command for each of the plurality of electro-mechanical actuators and adjust the speed command of each of the plurality of electro-mechanical actuators using a common reference parameter to synchronize movement of the plurality of electro-mechanical actuators together.
