| 摘 要： | 针对一步法注吹中空制品一模多腔模具在加热过程中因散热问题引起不同排布模腔的温度不均匀问题,提出采用LabVIEW架构解耦控制系统软件,应用其开发出符合系统需要的虚拟仪器,并在此基础上,研究在LabVIEW环境下实现解耦控制。实时控制结果表明,解耦后的系统可以使各个模腔之间的控制不互相干扰,很大程度上提高了温度控制的效果和精度。

| Abstract: | During the one-step injection blowing of hollow products using the multi-cavity mold,the problem of uneven temperature distribution in each cavity often happened.A decoupling control system was built by LabVIEW to solve the problem.And a virtual instrument was developed which could realize tempature decoupling control under the LabVIEW environment.The real-time control results showed that the decoupled system could control the temperature of each cavity separately,and could improve the effect and precision ... |
