Abstract:Despite the robustness and fast dynamic response, direct torque control (DTC) exhibits relatively large ripples in torque and flux during steady-state operation. Mitigating these ripples depends on designing a pulse selector to identify the optimal voltage vector at every control cycle, which has been reported with different structures in the literature. Hence, it is becoming increasingly crucial to comprehensively understand the criteria used in pulse selection and analyze their impact on the overall DTC perf… 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.
