Theory lovers corner

This is the section intended to explain some interesting theoretical features of the Arduino SimpleFOClibrary implementation. For now, I have briefly written only about few topics, but the plan is to cover much more topics and much more in depth.

Torque control using voltage

Short explanation and justification of the torque control using voltage instead current.

Field Oriented Control algorithm

A brief overview of implemented modulation methods and the main principles of the FOC algorithms for BLDC motors.

Low pass filter theory

Low pass filter differential equation and implementation details.

PID controller theory

PID controller differential equation and implementation details.

Sensor-Motor alignment procedure

Explanation of the motor and the position sensor alignment procedure and the importance of the initial rotor position.

Current sense alignment procedure

Explanation of the automatic current sense alignment procedure.
