BLDC control simulator

Simulation of different BLDC control algorithms written in MATLAB.

Currently implemented algorithms

1. Square-Wave Commutation Control (Robust and easier for implementation)

• PI speed control
• Hysteresis current control
• Trapezoidal back EMF model
• Sensing of rotor position sector with back EMF

2. Field-Oriented Control (Has better efficiency and lower noise sound in theory)

• PI speed control
• DQ current control with PI control and SVPWM
• Sinusoidal back EMF model
• Assumed the rotor position is known
