Design of Sensorless Brushless DC Motor Control System
Research of control system for BLDC motor without position sensor based on DSP(TMS320F28027),this system adopts high voltage side power tube PWM way,and uses intelligent power module(IPM).The hardware component and software design solutions for this system based on DSP are described.This system can be convenient in digital control system based on method of realization,simplified hardware structure,and make motor get effective control.
