BLDC_ESTIMATOR


The brush less DC (BLDC) estimator computes the rotor position based on motor parameters, voltage,and current values. The block also estimates motor speed. The algorithm is based on back-emfestimation and filtering.


Features and Benefits


  • Estimates the rotor position using PLL based approach
  • Uses measured current and generated voltage for estimation
  • Uses filters for back emf and speed
  • Operates in per unit, where 2^16 represents rated values
  • Documentation
