Subdivision Error Analysis and Compensation for Photoelectric Angle Encoder in a Telescope Control System
As the position sensor, photoelectric angle encoder affects the accuracy and stability of telescope control system (TCS). A TCS-based subdivision error compensation method for encoder is proposed. Six types of subdivision error sources are extracted through mathematical expressions of subdivision si...
