Abstract
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.
