Abstract
The present invention provides methods, systems, and apparati for fail passive error detection and control of a linear actuator recentering system. In an exemplary aspect of the present invention, linear actuator controls are designed to be fail passive. In one exemplary embodiment of the present invention, a recentering device' is provided which receives a signal from an independent motion direction sensor and enables continuous monitoring of a recentering function, thereby detecting recentering control failures. In another exemplary embodiment, the present invention comprises a recentering motor control commutation device, an actuator movement direction sensor and an inverse commutation device for determining a centering polarity. The centering polarity is further provided to an aircraft control system which suitably provides continuous verification of the recentering commutation by comparison to linear actuator position determined by another sensor. In accordance with another exemplary embodiment, after detecting the failure of a control component, a brake is immediatelyset.
