基于ARM+DSP的谐波实时闭环控制系统设计

Design of harmonic real-time closed-loop control system based on ARM+DSP

传统的谐波实时闭环控制系统抗干扰能力差,系统延时时间长。针对这一问题,基于ARM+DSP设计了一种新的谐波实时闭环控制系统,利用DSP模块、上位机ARM模块和脉冲宽度调制主回路模块构建系统硬件结构图,通过数据存储、命令控制、数据发送、信息存储等步骤完成软件工作,实现软件的通讯、存储、控制、显示等工作。为验证控制系统工作效果,与传统系统进行实验研究,结果表明,设计的实施闭环控制系统具有很强的抗干扰能力,延时时间短。

The traditional harmonic real- time closed- loop control system has poor anti- interference ability and long system delay. To solve this problem,a new harmonic real- time closed- loop control system based on ARM+DSP is designed. The hardware structure of the system is constructed by using the DSP module,the upper ARM module and the main circuit module of pulse width modulation. The software work is completed by data storage,command control,data transmission,information storage and so on. The communication,storage,control and display of the software are realized. In order to verify the effectiveness of the control system,the experimental results with the traditional system show that the closed-loop control system has strong anti-jamming ability and short delay time.
