【摘要】 为实现无刷直流伺服电机的精确可控性,选用TI公司的TMS320F2812 DSP作为控制核心,建立了无刷直流伺服电机全数字三闭环伺服控制系统。并介绍了该控制系统的硬件结构、实现方案以及软件设计。经实践证明,该系统不仅成本低、结构简单、方便扩展,而且电机运行平稳、定位准确、转矩波动小、速度控制灵活。更多还原

【Abstract】 To realize the precise control of the brushless DC servo motor(BLDCSM),proposed a digital control sysrem of BLDCSM with three-closed-loop using TMS320F2812 Digital Signal Processor(DSP) of TI.The method of hardware electric circuit design,realization means and software programming were presented in detail.The practice shows that the control system has simple structure,low cost and good control function,such as the motor runs stably with accurate location,small torque fluctuation and agile control of speed.更多还原
