Abstract:Currently, a high-precision tracking control system is required for a large-capacity optical disc drive system. This paper proposes a new full field-programmable gate array (FPGA) tracking control system based on an error-based communication disturbance observer (ECDOB) considering the time delay of an optical disc drive system. The FPGA control system may have a large influence on both the integer time delay and the non-integer time delay of the control system. In order to consider the time delay, this study … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
