A MODEL OF A PROGRAMMABLE SERVO MOTOR CONTROL SYSTEM WITH A LIMITED NUMBER OF PERIPHERAL COMPONENTS

This article discusses the tasks and requirements necessary to implement a model of a programmable servo motor control system with a limited number of peripheral components. The main goal is to develop a compact and mobile research bench capable of monitoring the rotation speed of a servo motor in real time. The model of a programmable servo motor control system with a limited number of peripheral components is an approach to creating highly efficient and compact motion control systems in industrial applications. The concept of this model is based on the integration of microcontrollers and specialized chips for controlling motors and other peripherals, which significantly reduces the number of components used and improves the overall performance of the system. A small DC motor is used as an actuator in the model. The speed of its rotation is regulated through pulse width modulation by changing the average value of the voltage applied to the motor windings. The control object is a platform with four servo motors. The liquid crystal display shows the current engine speed, expressed in revolutions per minute. To implement the model, technical requirements are defined, a block diagram of the device is developed, the selection of the element base and calculation of power consumption are performed, the assembly scheme of the device model is described, an algorithm and a control program are developed. During the testing process, conflicts in the operation of technical systems were identified and ways to improve the overall performance of the system were proposed. A block diagram of the device has been created and the process of assembling the physical layout is shown. The control algorithm used is considered and the results of the model's operability are demonstrated.
