摘要： A system that improves on known systems for reducing output torque by a motor in the event of a jam may include an electromechanical actuator (EMA), a motor configured to drive the EMA and a controller. The controller may be coupled to the motor and configured to receive a speed of the EMA and a position of the EMA. The controller may be further configured to determine whether a jam of the EMA is imminent or is occurring according to the EMA speed, EMA position, and a known range of motion of the EMA, and to provide an input signal to the motor to reduce a torque of the motor if a jam of the EMA is imminent or is occurring.

摘要： A system having a position sensing algorithm for determining a position of an electro-mechanical actuator (EMA) stroke includes a first rotary component supported for rotation about a first axis, and a second rotary component supported for rotation about a second axis. A first rotary encoder may be configured to generate an output based on an angular position of the first rotary component, and a second rotary encoder may be configured to generate an output based on an angular position of the second rotary component. The first and second rotary components may define a ratio such that the first and second rotary encoders generate unique combinations of outputs for an entire stroke of an EMA. A decoder may be provided having a position sensing algorithm that determines a position of the EMA stroke based on the ratio between first and second rotary components and outputs from first and second encoders.

摘要： An electronic control architecture for an aircraft actuation system may include a first channel and a second channel. The first channel may be configured to receive one or more inputs comprising a movement command, to produce an output to control a component of the system, and to receive feedback from the component respective of movement of the component. The first channel may comprise a fault detection module configured to compare the feedback to the command to determine if the first channel is functioning properly. The second channel may be configured to receive the one or more inputs and, if the first channel is not functioning properly, to produce an output to control the component.
