Abstract
A comparative study of open loop and closed loop dc motor transfer function and block diagram, PI controller, speed - torque characteristics and MATLAB simulation of three phase ac-dc thyristor converter-fed dc motor drive is presented. The simulation of converter-fed dc motor drive is studied in detailed, employing the SimPowerSystems in MATLAB Simulink because it has been found to offer better overall performance among other programming software. A Proportional plus Integral (PI) controller is design to reduce the system errors and improve the dynamics responses. The constant Kp and K, in PI controller can be changed to meet the acceptable performance. This project compares a various study in designing the converter-fed dc motor drive with and without system feedback and simulates drive under different loading and speed references. By increasing the constant Kp and K, tends to reduce the systems errors and improve the overshoot and settling time. However, large Kp and K, will worsen the transients' stability. A good controller will change back the motor speed to the normal value due to the change of load torque. The proposed converter is designed, constructed and tested in the lab using the separately excited dc motor. The experimental results are shown to be in good agreement with the simulated results.
