Abstract: The digital controller based on DSPTMS320F2812 for implementing position servo control of a short-stroke linear DC motor is designed.The hardware circuit of the digital controller is developed by using bus-isolated technique.A 16-bit analog-to-digital converter,a 16-bit digital -to-analog converter and testing circuit of linear displacement are presented.The applying results verify the feasibility of the hardware circuit of the digital controller.

摘要: 为了实现短行程直线直流电机的位置伺服控制,设计了一种基于DSPTMS320F2812的数字控制器。数字控制器的硬件电路采用总线隔离驱动技术进行了系统扩展,主要对16位双极性A/D转换器、16位双极性D/A转换器和直线位移检测电路的原理及实现方法进行了描述。实际应用结果表明,基于DSP的数字控制器的硬件设计是合理的,并能可靠的运行。
