数字信号处理器(DSP)在现代控制系统中的应用

Application of Digital Signal processors in Modern Control System

控制理论和高性能处理器的发展为先进控制技术的工程实现提供了条件。数字信号处理器(DSP)具有专门的高速结构和精简指令集,这使得DSP能在一个机器周期内执行"信号处理"类型的操作。因此,DSP很适合于执行现代控制算法。本文回顾了DSP的主要特征和控制功能。简述了DSP在控制系统中的应用,最后描述了DSP在现代控制系统中的应用前景。

The developments of control theories and highperformance processors offer an opportunity for the engineering implementation of advanced control techniques. Digital Signal Processors(DSP)have special high -speed architecture and reduced instruction sets which excute'signal - processing 'type operations in a single machine cycle. DSPs are therefore ideal for modern control algorithms. This paper reviews the DSPs' key features and control functions ,and introduces the applications of DSPs in control system briefly. Finally,the application prospect of DSPs in modern control system is described.
