МОДЕЛЮВАННЯ BLDC МОТОРУ ІЗ ЗАДАВАННЯМ ЗВОРОТНЬОЇ ЕРС І ВИКОРИСТАННЯМ JULIA

Modern technologies in the field of electrical engineering and automation require constant improvement and development. One of the key aspects of this development is the use of brushless permanent magnet (BLDC) motors. BLDC motor control methods play a key role in ensuring the efficiency and reliability of their operation. Until recently, simulation of these motors was a complex task, requiring excessive costs for computation resources, equipment and software. An important task in the development of motor control systems is the development and use of motor models. In modern motor control systems, modeling is used not only in the development process - the motor model can be an integral part of the control system, according to which control signals are calculated in real time. Processes in motors are described by systems of differential equations, and there are many methods for numerically solving these systems. The vast majority of these systems are built into relatively complex automatic design systems, and modeling control systems requires a significant amount of computing resources and studying the specifics of these systems. The search for an effective tool for modeling the motor and the control system should also take into account its availability for the scientific community and developers from the point of view of software ownership.The article presents the simulation model of a BLDC motor with simplified DC and full 3-phase electrical parts. The presented model describes the motor directly in the differential equations and allows you to quickly simulate processes in the motor and their changes under the influence of external variable parameters. The described model was created using programming language Julia perfected for mathematical calculations. Model allows to simulate motor operation under Variable voltage and load. The part of the model that generates external disturbances and control signals allows to simulate various forms of 3-phase voltage without complicating with external components or generators. The article presents the motor control results from 3-phase voltage and an autonomous voltage inverter.
