Abstract:In order to improve the speed control performance on the heavy load driving system of servo press, a control strategy based on speed observer with load torque identification and feed-forward compensation was proposed. It can identify and compensate the actual applied load torque by adjusting the machine quadrature axis current in real time. By identifying the problem in the traditional current feedback decoupling control scheme, a current vector control strategy based on voltage feed-forward decoupling control… 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.
