基于DSP的多轴运动控制器研究

摘要

According to the development and current situation of DSP at home and abroad. Using high-speed computation ability and rich resources of TMS320F28335 chip to achieve higher real-time demand motion control in numerical control system (linear interpolation, continuous interpolation, position control, Serial communication, etc). On that basis, this paper discussed realization of hardware and software design method of this controller. Such movement controller has the perfect function and excellent performance, it often provides the multi-axis motion coordination control on the plate, and has higher control precision.%针对国内外DSP的发展情况及现状,利用TMS320F28335芯片的高速运算能力和丰富资源实现数控系统中实时性要求较高的运动控制（直线插补、连续插补、位置控制、串行通讯等）。在此基础上,就该运动控制器的硬件及其软件设计的实现方法进行了讨论。这类运动控制器功能完善、性能优越,通常能提供板上的多轴协调运动控制,控制精度较高。
