Bridging the Chasm: From “Tuning” to “Design”

In the world of industrial motion control, I see many engineers struggling with the “Chasm” between theoretical research and product implementation. They often rely on empirical PID tuning, spending countless hours on trial and error.

I founded SakaLib to change that.

My mission is to provide an environment where every engineer can master practical control theory and implement it directly into actual machines.


What I Offer

SakaLib provides solid knowledge to achieve professional-grade motion control:

1. Control Theory for Motion Control

Move beyond PID. I share how to design robust and high-performance motion control systems based on control theory explained for practical, real-world use.

2. Python for Control System Design

Simulation is the key to successful design. I developed and released pylib-sakata, an open-source library that allows you to design and verify control systems in a free, accessible environment.

3. Real-time Implementation with TwinCAT

Theory is only as good as its implementation. I provide expert tips on using TwinCAT and EtherCAT to achieve the synchronization, real-time performance, and high-speed sampling required for cutting-edge motion control.

Training program

Bridging the gap between advanced control theory and industrial implementation within Japan. For those who want to master these skills rapidly, I offer an intensive 3-day training program. To learn more about my training program, please visit Training.
