基于DSP与CAN总线的跟踪伺服控制器设计

Design of tracking servo controller based on DSP and CAN bus

在分析跟踪伺服系统特点的基础上,以TI公司DSP芯片TMS320F2812作为主控制芯片,采用CAN总线与上位机通信,设计了基于DSP与CAN总线的多轴跟踪伺服运动控制器。给出了该控制器的功能和硬件结构,以及软件流程设计。实验结果表明,该控制器具有高集成度、灵活性、实时性、模块化的特点。

The fatures of tracking servo system is analyzed, regards TI＇s DSP chip TMS320F2812 as the main chip, adopted CAN bus to communicate with computer, tracking servo controller based on DSP and CAN bus has designed. The function and hardware struction of the controller, and software flow design has been given. The practice proved that the controller has four advantages： high integration, flexible, timing, and modularization.
