awesome-FOC-motor-control · A Path-Based Learning List for FOC Motor Control

简体中文版（full version）请见 README.md · This is a condensed English overview written for an international audience.

A curated, path-based learning repository for FOC / PMSM / BLDC motor control — from physics intuition to production delivery. There is no shortage of motor-control materials; what's missing is the right order.

This is not a link dump — it's a seven-layer skill tree. Motor-control knowledge is strictly layered: every upper-layer skill assumes the ones below it are already in your hands. If you climb before the lower levels are built, you won't just learn slowly — you'll get stuck at a fixed point, and you'll blame the algorithm, the parameters, or the hardware when the real problem is the missing foundation.

The Seven-Layer Skill Tree

L6  Production delivery   Thermal / EMC / protection / production consistency / cost
L5  Sensorless observers  Sliding-mode / Luenberger / EKF, blind start + handover
L4  Speed / position loops  Outer-loop PI, nested bandwidths, inertia matching, feedforward
L3  FOC current loop      Clarke/Park, SVPWM, current-loop PI, timing budget
L2  Measurement           Oscilloscope triggering, current sensing, encoder alignment
L1  Power stage           Three-phase bridge, MOSFET on/dead-time, PWM, six-step commutation
L0  Physics intuition     Magnetic fields, back-EMF, KV/Kt, commutation

Quick start: a dev board with three-phase drive (e.g. B-G431B-ESC1 or a SimpleFOC board) + a brushless motor + an oscilloscope. For the first three months: get the motor spinning with six-step commutation, get the waveforms right on the scope, and hand-write a FOC current loop.

Production-grade C templates	tools/: PI controller (anti-windup, ISR-safe), lock-free ring buffer, and SVPWM — 7-segment sector method with limiting, all 无动态内存/无递归

中文 marks content that is primarily in Chinese; for those, English readers may rely on code, waveforms, and official vendor links. The full list, all layer annotations, and the complete debugging write-ups live in the 中文 README and under resources/.

How to Use This List

1. What to learn first — climb the tree from L0 up. Confirm L0 physics intuition, L1 power stage, and L2 measurement by their pass criteria before going on. The first three layers are the foundation of everything else.
2. What to build — at each new layer, do that layer's acceptance action before moving on (e.g. L2: capture PWM / phase current / encoder waveforms on your own, without a library). Whenever something can be hand-written with the library off (transforms, SVPWM, current loop), write it by hand.
3. Where to look when stuck — return to that layer's deep material: the article index, the per-layer resources/ documents, and the debugging & measurement notes for the 9 methodologies.

One line: don't force higher layers before the foundations are in; verify by doing, not by collecting.
