Design and Development of a Speed Control System for a Stepper Motor using the PIC18F4550 microcontroller and its interface Status: In press

Abstract

This article focuses on the design and development of a stepper motor control system, with a subsequent focus on its application in a crane that will lift a small mass vertically. Every aspect of the implementation has been examined in detail, from the choice and configuration of the 28BYJ-48 motor to the implementation of control interfaces such as the 4x4 matrix keypad and RS232 communication. In this system the control resides on the PIC18F4550 microcontroller. The control approach has been focused on two modes: manual and automatic. In manual mode, the matrix keyboard has been used to allow direct interaction with the crane, adjusting parameters such as speed and direction. On the other hand, the automatic mode has demonstrated the ability to perform predefined movements, with a specific number of steps that ensure positioning accuracy. Overall, this study has presented a comprehensive electronic control system, offering applicability in various technological areas. The stepper motor has been highlighted as a key component to achieve controlled and precise movements. As research in this field progresses, this system provides a solid foundation for future improvements and optimizations in similar systems.
