Field notes from the workbench.

Deep dives into the engineering behind precise machines — written by the people who build them.

How to Tune a PID Loop: A Field Guide

The procedure we actually use in the field: preparing the loop, three tuning methods that work, the implementation details that make or break them — and a symptom table for when it misbehaves.

Writing an FOC Controller from Scratch

The whole algorithm is forty lines built on one idea. Clarke, Park, two analytically-tuned current loops, SVPWM, an annotated ISR — and the alignment gotchas that eat the first two weeks.
