摘要
Abstract
As the SVPWM is applied to motor control system widely,the estimation of rotor speed and position is vital. To improve the accuracy of estimation,a SVPWM control strategy based on Hall sector time tracing algorithm was proposed,which was aimed at electrombile BLDCM system upon low-resolution position sensors. Then,BLDCM simulation model based on SVPWM control strategy was built by Matlab/Simulink. The simulation reveals that Hall sector time tracing algorithm has a good real-time and dynamic performance,and has strong anti-disturbance capacity, compared to measuring method of intervals average velocity. Finally,experimental platform based on STM32F303 was designed,and the proposed algorithm had been researched by experiments. Result validate the algorithm can increase estimation accuracy of motor rotor speed and position.关键词
