Reliable Control of PMDC Motor Speed Using Matlab [ READ ]
M. O. Charles, R. C. Okoro, I. A. Ikposhi, D. E. Oku
This research investigated several controllers designed to control the speed of a 380-volt permanent magnet DC motor set to rotate at a speed of 45 rads/sec. The aim is to design a controller which is robust and reliable, with a good disturbance rejection suitable for use in any industrial equipment or domestic appliance which rotates at a speed of 45 rads/sec. The system modeling was carried out using simulink for proper analysis of the time responses of the various controllers. The reliability of the system model was tested with a torque of 10Nm and the responses show that the cascade-PID controller amongst all controller designs tested can produce a stable, reliable, and robust but not very sensitive system, while the ordinary PID controller can produce a highly sensitive, but less stable system.
