Two
feedback loop better than one (PDF)
A motioncontrol
method using two feedback sensors and PID functions divided between their
loops ensures superior accuracy. Dual-loop control systems seems to be
an ideal way to increase productivity, accuracy, and dynamic performance.
It can also lower costs, simplify designs, and reduce wear.

An
Interference-Based Incremental Optical Encoder
An interferometric
technique allows an incremental optical encoder to read light signals
transmitted through slots as narrow as 1 micron on the code disc, greatly
increasing precision of the device.

Application
of Rotary Optical Encoders and Resolvers in Brushless Servo Motors
This paper
discusses the application issues associated with the use of resolvers
and optical encoder as the primary feedback element on a BLDC Servo motor.

Motion
control and Optical Encoders (PDF)
Optical encoders
are critical components in systems with rotating shafts or parts. This
article briefly looks into the construction, output types and mounting
of rotary encoder.
