Director Introduction
Motor Control & Robotics Drive Systems Expert | Springer Author | Founder of YEHSTALK.SCHOOL | NIW Permanent Resident
I am a motor control architect with over a decade of industry experience and 20+ years in motor control research and development, working at the intersection of electromagnetic physics, high-performance control algorithms, and simulation-driven engineering.
My work focuses on bridging theoretical modeling and real-time industrial implementation for robotics, EV drivetrains, and precision servo systems.
Three years ago, I made a pivotal decision to step beyond the traditional industry “ceiling” in Taiwan. I transitioned from a senior technical role to becoming an international educator and author. This leap led to the publication of AC Motor Control Loop Design (Springer Nature) and the founding of YEHSTALK.SCHOOL, now the largest Mandarin-speaking learning community for electric drive engineering with over 30,000 members.
📘 Published Authority
Author of AC Motor Control Loop Design (Springer Nature, 2026), a monograph on control-loop modeling, delay compensation, and simulation-driven motor-drive design. My work integrating neural networks (CMAC/ANN) with field-oriented control (FOC) has been recognized by international technical publishers for addressing nonlinear motor-system constraints.
⚡ System-Level Expertise
Beyond control-algorithm design, I maintain a strong foundation in electromagnetic modeling (ANSYS Maxwell), enabling optimization of motor-drive systems from physics-level design through real-time embedded implementation.

AC Motor Control and Simulation Techniques:
Mastering the Core Algorithms Behind Electric Vehicles and Variable-Frequency Drives
This book provides a comprehensive exploration of induction motors, permanent-magnet synchronous motors (PMSMs), and brushless DC (BLDC) motors, including their operating principles, physical mechanisms, and control strategies. It also includes extensive MATLAB/SIMULINK simulation examples that readers can use to bridge the gap between theory and practical implementation while developing physical intuition and a control-system design mindset.
In addition to fundamental motor-control theory, the book covers many practical engineering topics, including PWM inverter modeling, motor-parameter self-identification algorithms, control-loop design techniques, sensorless control methods, field-weakening control, and per-unit system modeling. All concepts are supported by MATLAB/SIMULINK simulations and verification, enabling readers to gain both valuable knowledge and hands-on capability in AC motor-control theory and practice.
AC Motor Control Loop Design (Chinese version)
In the field of AC motor control, the design of digital control loops has long been a challenging topic. As technology advances, the demand for highly efficient and stable motor-control systems continues to grow, driving the need for deeper understanding and application of classical control theory to meet modern engineering requirements.
Digital control systems have become the dominant approach for implementing AC motor-control technology. However, digital systems inherently introduce delays, including computational delay, sampling delay, and output delay. These delays inevitably reduce system stability. If such delays are not properly considered during the control-loop design stage, the designed system bandwidth and stability may differ significantly from actual system performance.
This book approaches AC motor control-loop design—covering current, speed, and position loops—from the perspective of classical control theory concepts such as bandwidth, phase margin, and gain margin, while explicitly incorporating delay effects in digital systems. The resulting simulation models closely resemble real motor-control systems.
By constructing simulation tools that accurately reflect physical systems, engineers can significantly reduce development and testing costs. At the same time, such models serve as an effective foundation for building proprietary intellectual property, strengthening independent innovation capability and core technical competitiveness.
