Numerical simulation of BLDC electrical drive systems closed-loop control and sensorless control

In this paper is presented an accurate and fast running Matlab®/ Simulink® closed-loop model and sensorless model of the BLDC electrical drive system. For analysis, an experimental system with a Hurst type BLDC motor was choosing. The numerical simulation results confirm that the mathematical model is accurately enough and reproduces with sufficient precision physical behavior of the electric drive system.
