基于DSP的三维打印机控制系统研究

Control system for 3D printer based on DSP

针对目前国内自主研发的三维打印机加工精度不高的问题,设计了一种新型三维打印机控制系统。该控制系统分为硬件系统和软件系统,硬件控制系统核心为电机运动控制和温度控制,软件系统主要实现PID算法在DSP芯片中的嵌入。通过PID控制和模糊控制的控制原理进行了控制原理的确立,在Matlab环境中进行了控制系统模型的建立与仿真,最终通过DSP芯片实现了三维打印机控制系统硬件平台的搭建。研究结果表明,采用新型控制系统的三维打印机加工性能得到了显著提高。

Aiming at solving the problem of low machining accuracy in domestically-developed three dimension printers （3DP）,experimental study on a new 3DP control system was carried out.The control system was composed of hardware system and software system.The hardware system was established through motion control of motor and temperature control.PID arithmetic applied in DSP was realized in software system.Control principle was set up through PID control and fuzzy control.Model of control system was set up and simulated through Matlab,hardware platform of 3DP control system was set up through DSP.The experimental results show that the machinability of new 3DP is significantly improved.
