基于MAX5307和DSP的多回路测控系统设计

提出了一种多回路测控系统的设计方案。该方案仅使用一个DSP(数字信号处理器)及一个多通道集成的D/A转换器件MAX5307,不仅同时保证了多个测控回路的实时性及控制精度,而且实现简单,成本低廉。文中结合实际系统,给出了其具体的硬件和软件实现。该方法具有广泛的适用性,对类似系统的设计具有参考价值。

In this paper,a design concept of multi-loop measurement and control system is proposed.Only one digital signal processor(DSP) and one multi-channel digital to analog converter(DAC),MAX5307,are used in it.With this design,each individual control loop in the system can achieve high real-time performance and precise control output.Moreover,it is simple and the cost is very low.As an example,the details of its hardware and software implementation are provided here.This design can be used to many other applications and can be used as reference for the development of similar systems.
