Abstract:
DC motor controlling is known to be one of the most crucial application in the
Engineering world, where precise motion control is commonly found in industrial and
commercial applications. Hence, learning the fundamentals of DC closed-loop motor control is
beneficial for undergraduate students studying Engineering courses. However Due to the ongoing
unprecedented economic crisis in Sri Lanka, the lack of access to electronic components, has
become very challenging and in turn, affects implementing and testing of the theories on real
prototypes. Hence In this paper, a low-cost ARM® based DC motor embedded control platform
is presented so the students who are following control courses can implement their own prototype
for an affordable cost using only a few common components. The closed-loop control algorithm
is designed by using the PID controller, tuned the system using the classical: trial & error method
and tested the system responses in real-time, according to different load conditions. Moreover,
ARM® based STM®32F407G micro-controller has been used to program the controller and keil®
uVision® software is used as the programming IDE. Using MATLAB® and Simulink® platforms,
a comparison of the system responses with no-load, lite load and full-load conditions has been
presented.
