Abstract
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.
