G. Murugananth, S. Vijayan, S. John Alexis, S. Muthukrishnan . A Comparative Analysis of PI, PID and Anti-Windup PI Schemes for PMDC Motors. International Journal of Computer Applications. 57, 2 ( November 2012), 21-25. DOI=10.5120/9086-2749
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 the performance of a closed loop chopper controlled drive is evaluated. The chopper controlled drive has an inner current control loop and an outer speed control loop. The outer control loop employs a PI, PID and anti-windup PI controller for the speed control of the PMDC motor. A comparative study is made between conventional PI, PID and the anti-windup PI controllers. The system is simulated using Matlab/Simulink and the properties of these controllers were measured and tabulated. The simulation results inferred that the proposed closed loop system with anti-windup PI controller gives better performance and the system can be used for the control of the PMDC motor in orthopedic surgeries.
