Abstract: Orthopedic surgical simulators are used by the trainee surgeons to drill the bones and place the screws. These simulators use PMDC motors for bone drilling. In this paper a closed loop chopper controlled drive is proposed and evaluated. The chopper controlled drive has an inner current control loop and an outer speed control loop. The outer control loop employs a conventional PI controller for the speed control of the PMDC motor. The anti-windup PI controller based system is proposed in order to enhance the performance of the system. The system is simulated using Matlab / Simulink and the performances of various anti-windup schemes are analysed. The properties of these controllers were measured and tabulated. The simulation results inferred that the proposed closed loop system with tracking anti-windup schemes can be used for the effective control of the PMDC motor in orthopedic surgeries.
