Control Speed of BLDC Motor Without Position Sensor
Since R2024b
This example shows how to control the speed in a brushless direct current (BLDC) electric drive without a position sensor. A DC voltage source feeds the BLDC through a controlled three-phase inverter. The Control
subsystem implements the sensorless speed control strategy. A hysteresis controller controls the phase currents. The Scopes
subsystem contains scopes that allow you to see the simulation results.
