摘要
为实现无刷直流电机的精确可控性,应用TI公司的TMS320LF2407ADSP作为控制器,建立了无刷直流电机全数字三闭环控制系统。并介绍了该电动机控制系统的硬件结构、软件流程和控制算法采用变速积分PID算法。经分析该系统不仅成本低、结构简单、方便扩展,而且系统响应速度快,稳定性好。
To realize the precise control of the Brushless DC Motor（BLDCM）, this paper proposed a digital control system of BLDCM with three-closed-loop using TMS320LF2407A Digital Signal Processor （DSP） of TI. The method of hardware electric circuit design and software programming were presented in detail. The digital PID control algorithm with the variable-integrator was also used in the system. The analysis shows that the control system has simple structure and good control function, such as good stability performance,fast response abililty and etc.
