基于DSP2812无刷直流伺服电机控制系统的开发

Research and Development of the Brushless Direct Current Servo Control Motor's System Based on DSP2812

为实现无刷直流伺服电机的精确可控性,应用TI公司的TMS320F2812 DSP作为控制器,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、控制策略和实现方案。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。

To realize the precise control of the Brushless DC servo Motor（BLDCSM）,a digital control system of BLDCSM with three-closed-loop using TMS320F2812 Digital Signal Processor（DSP） of TI Company was set up.The method of hardware electric circuit design,control strategy and realization means were presented in detail.The practice shows that the control system has simple structure,low cost and good control function.The motor runs stably with accurate location,small torque fluctuation and agile control of speed.
