Design of an automatic focus control unit using fuzzy logic

摘要

Abstract: This paper discusses the development of an automatic focus control unit (AFCU) for optical tracking instrumentation at White Sands Missile Range, New Mexico. The telescope system is known as the distant object attitude measurement system (DOAMS) and is used for optical data collection including attitude and miss-distance information. The AFCU will be given only target range and will provide a highly accurate focus. Fuzzy logic was chosen as the control method for this project. !4
