| Abstract: | This paper seeks to design a control system for an efficient and energy-saving brushless DC motor. LS052A-Cb is a general-purpose microcontroller in made in China that supports parallel multi-core multi-tasking processing. After studying the basic principles of SVPWM, with space vector pulse width modulation technology, and via counter EMF position detection is achieved under the sensor-less mode. And speed detection and current collection using dual-loop PID control strategy, speed control experiment of the brushless DC motor is carried out. The conclusion of feasibility of a new type of brushless DC motor control system of the program is obtained and proven of great value in application. |
