1. A fault tolerant actuation system comprising:
an actuator having a position;
a first sensor measuring a first parameter associated with the actuator;
a second sensor measuring a second parameter associated with the actuator;
a sensor fusion module receiving data from each of the first sensor and the second sensor and executing a sensor fusion process on the data received to estimate the position of the actuator; and
a fault detection module configured to:
receive data from the first sensor and the second sensor;
receive sensor fusion data from the sensor fusion module;
compare the data received from the first sensor and the second sensor with the sensor fusion estimate;
identify an error in the data received from the first sensor or the second sensor based on the comparison; and
determine a fault exists in the first sensor or the second sensor based on the error.
