In aviation the term fly-by-wire means that the control surfaces of an aircraft are operated by actuators rather than via cables and rods, with electrical signals transmitting information from the ...

Encoders are widely used to help control machine position and speed. Typical encoder output, a series of quadrature signals, consists of two full square Encoders are widely used to help control ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

Direct drives place rigorous demands on position-signal quality. Optimum measuring signals increase the quality of the machined workpiece surface, reduce vibration in the machine frame, stop excessive ...

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...
