The Motor drive employs an inner current and outer speed control loop with a conven- tional or modern controller. To enhance the performance of the drive, this paper proposes a Brain Emotional Logic Based Intelligent Controller based chopper drive. The proposed drive scheme has been simulated using Matlab/Simulink and physically realized for validation. A comparative analysis has been made between the conventional PI controller based drive and the proposed system in order to prove that the proposed scheme has an edge over the traditional PI controller scheme counterpart.

Introduction Osteosynthesis is the surgical practice of reducing and stabilizing fractured bones using mechanical connectors such as metal plates, wires or screws. It is done in three phases namely screw insertion, tightening and stripping. In Osteosynthesis low power electric motors such as permanent magnet DC (PMDC) motors are used to make joints in the fractured bones. Depending on the nature of fracture, a metal plate or screws will be attached with * Corresponding author.
