Chopper driven Permanent magnet DC (PMDC) motors are used to drill bone and fix the screws in orthopaedic surgeries. The drive of the motor employs a traditional or modern controller that has an inner current control loop and an outer speed control loop. As an alternative to traditional proportional integral (PI) controller-based chopper drives, this paper proposes a fuzzy-tuned anti-windup PI (AWPI) controller-based chopper for the speed control of PMDC motors used in orthopaedic surgeries. The proposed scheme was simulated using Matlab/Simulink and physically realized for validation. It is ascertained from the performance analysis that the proposed fuzzy-tuned AWPI based scheme exhibits better steady-state and transient-state responses when compared with traditional PI and AWPI controllers.
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.
