Microprocessor based speed control of a chopper-fed d.c. drive
thesis
posted on 2014-02-12, 13:58 authored by Waleed M. SaidThe thesis is concerned with microprocessor-based
control of a d.c. drive system using armature voltage control
technique with a separately-excited, chopper-fed d.c. motor.
The chopper circuit has a full-bridge configuration employing
gate-turn-off (GTO) thyristors, and. is capable of four-quadrant
operation, making the drive both reversible and regenerative.
The control of motor speed is achieved by a completely digital
technique, which does not require any analog-to-digital or
digital-to-analog converters. A microcomputer, specially
designed and built, generates the triggering signals for the
GTO's by using the unipolar switching strategy, which is
accomplished totally by software using look-up tables (... continues).
