近年来，随着工业自动化的发展，工业设备越来越趋向于高效率化，作为执行元件的重要组成部分，电机必须具有精度高、速度快、效率高等特点，无刷直流电机的应用也因此而迅速增长。无刷直流电动机是在有刷直流电动机的基础上发展起来的。现阶段，虽然各种交流电动机和直流电动机在传动应用中占主导地位，但无刷直流电动机正受到普遍的关注。本文介绍了一种基于TMS320F2812 DSP的无位置传感器无刷直流电机控制系统。针对无位置传感器无刷直流电机转子位置检测进行了研究。简述了实现该控制系统的硬件组成和软件的设计方案及控制策略，并对控制系统进行分析。此系统可大大简化硬件结构，并使电机得到高效稳定的控制。

In recent yeas, with the development of industrial automation, industrial equipment increasingly tend to be high- efficiency, miniaturization and high intelligence. As an important part of the implementation of the actuators, the motor must have high precision, high speed, high efficiency, therefore, the application of BLDC (Brushless Direct Current) is increasing rapidly. The BLDC motor is developed based on brush DC motor. At this stage, the AC motor and DC motor are dominant in drive application, but the BLDC is a universal concern. This paper researches the rotor position detection, presents a control system based on DSP TMS320F2812 for position sensor- less BLDC motor. Besides, the paper analyzes the control system and describes the composed hardware, software design and control strategy. This system can greatly simplify the hardware construction, and control the motor efficiently and stably.
