【摘要】 本文以美国国家仪器公司的图形化编程语言LabVIEW8.0为开发平台,将虚拟仪器技术和神经网络技术相结合,利用神经网络对PID参数进行整定,建立了BP神经网络PID控制模型,并且应用于热处理炉炉温控制。本文阐述了炉温控制系统的硬件结构和PID控制器的设计方法,给出了炉温控制系统的软件设计。该温度控制系统应用于热处理炉的炉温控制中,取得了较好的效果。更多还原

【Abstract】 The paper builds PID control model based on BP neutral network,which takes graphical language LabVIEW8.0 by NI as development platform,connects virtual instrument with neutral network technology and set PID parameters with neutral network.Then we applicate the technology to temperature control system.This paper shows the hardware structure of temperature control system,the design method of PID controller and the software of this system.The application has shown that the system has good effects.更多还原
