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.
