About
Dr. Jack Yeh (Chih-Chun Yeh, 葉志鈞) is a Motor Control Architect, IEEE Senior Member (SMIEEE), and Member of the Institution of Engineering and Technology (MIET). He specializes in AC motor control, control loop design, system modeling, and digital motor drive implementation.He is the author of AC Motor Control Loop Design (Springer Nature), a practical reference on modeling, delay compensation, and simulation techniques for modern electric drives.Dr. Yeh is also the author of Modern Ronin: Reflections on Alignment, Growth, and Clarity, a bilingual reflective work exploring alignment, perception, growth, and the pursuit of a more authentic life.He is the founder of MotorControl.School, one of the largest motor control learning platforms in the Chinese-speaking engineering community, and the creator of a global motor control learning community of more than 30,000 engineers and students.His engineering philosophy can be summarized in a single sentence:“Theory must survive reality.”
Expertise
My expertise focuses on AC motor control, digital control loop design,
and practical implementation of motor drive systems.Key areas include:• Field-Oriented Control (FOC) and Direct Torque Control (DTC)
• Control loop design and delay compensation for digital motor drive systems
• MATLAB / SIMULINK–based motor control modeling and simulation
• Sensorless control of induction motors (IM) and permanent magnet synchronous motors (PMSM)
• Intelligent motor control using neural networks and CMAC architectures
• Electromagnetic and multi-domain simulation of motor drive systems using ANSYS Maxwell
• Practical engineering education in motor control and drive systems
Featured Work
