A forum was held to share the fundamentals of motor control technology and modeling expertise using Matlab and Simulink, both used in industrial settings. Many developers in the field participated in the forum, demonstrating keen interest in sharing motor control technologies used across various industries and product development.

The "2022 e4ds Industrial Motor Control Technology Conference" was held on the 22nd in the main auditorium of the Korea Conference Center. Hosted by e4ds News, the event covered fundamental motor control theory and advanced control techniques, and provided a platform to share motor modeling methods using MATLAB and Simulink.

Professor Lee Taek-gi of Hankyung University and President of the Korean Institute of Power Electronics presented the session on ‘Industrial Motor Control Technology.’ △Shared knowledge on basic circuit theory, AC motors, power conversion devices, and motor driving.

In the first half of the session, the professor explained the theory of circuits and AC motors and emphasized that “the life of an AC motor is a rotating magnetic field.”

In the latter session, the principles of power conversion, power conversion devices such as single-phase and three-phase rectifiers were covered, and the theory of DC motor drive and AC motor control, and the basics of vector control were lectured.

He emphasized, "The most fundamental aspect of a DC motor lies in the operation of a current controller," and explained the current controller formula. He also shared direct and indirect vector control methods, which control an AC motor like a DC motor.

In the following session, Kim Ryong, Director of the e4ds Electronics Technology Research Institute, introduced the e4ds Make Contest. He shared his motor control development experience and presented on the contest, which involved designing a motor control model. Ahead of the contest's Quest 3, participants attended this motor control technology conference to gain knowledge about motor control design technology.

“The e4ds make contest is a place where you can share fun development ideas while still being easy to participate in,” said Director Kim Ryong. “I hope the contest will become a community for developers.”
In the afternoon session, Lim Jong-su, CEO of Sujin Enterprise, conducted a hands-on demonstration of industrial motor control technology using MATLAB. Sharing his extensive expertise in MATLAB and Simulink, Lim lectured on the fundamental concepts of MATLAB and its application to DC motor modeling.

He presented a smoke detector sensor as a demonstration, emphasizing the importance of implementing algorithms capable of continuously measuring physical values. He added, "After learning the theory, you should be able to generate the formulas based on it into your own code," and also demonstrated a modeling method using MATLAB and Simulink. Various modeling was presented, including how to drive the STM32 MCU with code generated from Simulink.

Next, Lim Seong-il, Director of Technology at Texas Instruments (TI), introduced the diverse portfolio required for automotive system design. Amidst the growing trend of hybrid and electric vehicles, TI emphasized that its technology is focusing on OBC and conductor solutions.

TI presented a new integrated architecture for electrical and powertrain systems, stating that the trend is to integrate inverters, distribution units, high-voltage DC/DC, and OBC into powertrain systems.

“TI’s new MCUs, designed for hybrid and electric vehicle traction inverters, encompass both 5G security and integration solutions,” said Sung-il Lim, TI’s director of technology.
At this event, developers showed a high level of participation by asking numerous questions during the Q&A session and resolving their curiosity about motor control.

Meanwhile, details about the '2022 e4ds Industrial Motor Control Technology Conference' will be covered in the e4ds News July Monthly Briefing, which will be broadcast at 10:30 AM on July 29th.

Additionally, a self-driving technology seminar hosted by e4ds news is scheduled to be held in September. It is expected to share related solutions and technical knowledge, and provide an opportunity to find answers to questions you may have had through a Q&A session.
