High-Speed Stepper Motor Control: A PC-Based Approach with Wired Communication for Precise Motion Control

Abstract

Modern society's ubiquitous household goods and devices use stepper motors in a wide range of applications. In numerous industrial driving applications, the problem of sensing variables for control, such as position, velocity, or current, commonly arises. Given the high cost or environmental restrictions, it may be challenging to detect signals that precisely represent system variables, such as the absolute shaft position. When this happens, we are compelled to estimate all or some of the missing variables using a small quantity of data that could be noisy.The purpose of this project is to plan and construct a circuit that employs a microcontroller to fulfil the task of controlling the stepper motor through a keypad. As a result, the microcontroller's circuit can regulate both the step angle and the speed of the stepper motor. whenever the user types one of the keypad's many commands. This project describes in full how to link an extremely sensitive personal computer system with a high-voltage electrical device or a direct current/alternating current motor. We will be able to create the graphical user interface that will monitor and control the stepper motor's speed using the technology that has already been built. The project may be disassembled into its two constituent elements, the hardware and the software. Hardware for the suggested system, as well as how it will link to a computer through an RS232 serial connection port. We are creating an RS-232 connection between the PC and the controller to establish communication.
