The Design Controller of BLDCM Based on DSP

无刷直流电机是一种集功率半导体和永磁材料于一体的新型电机,无位置传感器无刷直流电机更是克服了传统无刷直流电机在恶劣环境下,位置传感器容易受到干扰而无法正常工作的缺点,扩大了无刷直流电机的应用范围。主要提出了基于数字信号处理器DSP(Digital Signal Processor)和复杂可编程控制器件(Complex Programmable Logic Device)构成的无位置传感器无刷直流电机的控制系统,详细分析了以TMS320F2812和MAX7000(EPM7032)为核心的控制电路、功率逆变电路和转子位置识别电路的工作原理。并对该系统进行了测试,测试结果表明,该系统抗干扰性强,鲁棒性好,启动迅速,效率高。

BLDC Motor is a new type motor based on power semiconductor and permanent magnetic material. Sensorless BLDC Motor extend the application range with the most advantage that it can operate normally in had condition. The design of senorless BLDC Motor control system based on DSP （ TMS30F2812 ） and CPLD （EPMT032） is presented, and the system scheme is proposed. The principle of control circuit based on DSP and CPLD, power inverter circuit and the location of rotor recognition circuit are analyzed. The performance of control system is tested. The result shows that the control system can achieve low torque ripple,smooth movement,starting fast and high efficiency running effects.
