Research on Sensorless Control system of BLDCM Based on TMS320F2812
An electronic control system for sensorless BLDCM is proposed.Normally,the back-emf signal has coupling noise from the PWM signal which is used to vary the speed of the motor.So it is difficult to detect the zero-crossing point accurately when the motor work at low speed.In order to improve the controllability of BLDCM at low speed,a new algorithm is presented.The control system is implemented from both hardware and software parts.And the experiments verified the good control performance and dynamic characteristics of the system.
