Abstract
A method for fault detection and accommodation for a controller and actuator system is provided. The method includes receiving, from a controller, a flag at an actuator in response to an excitation voltage and current falling below a threshold value, engaging a sensor in the actuator in response to receiving the flag, receiving, using the sensor a first load cell signal and a second load cell signal in response to the sensor being engaged, determining how actuator is operating brake based on the received flag, first load cell signal, and second load cell signal, adjusting a state of the actuator based on the determination, and reporting the state of the actuator by transmitting a report signal to the controller.
