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 the most widely used feedback devices for electric motor control, capable of delivering precise position and speed feedback for closed-loop performance. With numerous technology options ...

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 ...

Purdue University alumnus Sergey Zakharov, co-founder and chief technology officer of ZS Instruments, holds an optical encoder wafer created by a prototype of the company’s novel technology. ZS ...
