Barcode-based position control servo for high-speed conditions

摘要

A barcode-based position controlling method for high-speed Conditions was introduced to deal with the position control in some conditions where it cannot be done quickly and precisely using traditional methods.The position feedback will depend on the decoding of a specifically redesigned barcode with a special structure.By using the angle encoder and interpolation arithmetic,high precision position deviations can be attained.Then position correction will be done through the control algorithm and servo system.The design and decoding of the barcode and the method of obtaining extremely precise deviation are illuminated.In theory,this method of control servoing is very suitable for its real-time,high-precision and high-speed applicability.
