Experimental Validation of Fuzzy-Tuned AWPI Controller-Based Chopper Driven PMDC Motor

Abstract

Abstract 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.
