Abstract
The paper presents the development of a microprocessor-based controller for a separately excited d.c. motor drive system. The motor speed is controlled by adjusting the armature voltage, using a single-phase half-controlled converter. The synchronising pulses needed for the converter are generated by the microprocessor. Details of the required compatible hardware circuits and software programs are described. A mathematical model of the drive system is developed for steady-state and transient analyses. Simulation and experimental results are presented to show the system performance. The experimental set-up and its mathematical model provide an excellent facility to study and develop advanced digital controllers for the drive system.
