Abstract
The present disclosure provides an electromechanical brake actuator system comprising an electromechanical brake actuator coupled to a derived position sensor, the derived position sensor comprising a controller, a rotation sensor, and an output drive circuit. In various embodiments, the derived position sensor may be configured to receive a first motor shaft angular velocity at a first time, receive a second motor shaft angular velocity at a second time, calculate a linear translation distance, and sum the linear translation distance and a previous ram position to obtain an actual ram position.
