Advancing High-Speed Stepper Motor Control: A PC-Based Approach with Wired Communication

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. In cases like this, we are compelled to estimate all or a portion of the missing variables using a sparse sample of data that could contain noise. 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 cann 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 current motor. We will be able to create the graphical user interface that will monitor and control the stepper motor’s speed usi technology that has already been built. The hardware and the software, the project’s two component parts, can be separated into their own parts. The suggested system’s hardware and its connection to a computer through an RS232 serial port are both described. To establish communication, we are setting up an RS-232 connection
between the PC and the controller.
