摘要： 对于工业过程控制中有线控制存在的布线困难、可拓展性差、维护成本高等问题,本文设计并开发了具有丢包补偿GORC-PID (generalized open-loop response control-PID)算法的无线温度控制系统。以工业上通用的WirelessHART为标准协议,使用无线硬件设备搭建无线通信网络,替代有线通信方式,并以监视与控制通用系统(monitor and control generated system,MCGS)组态软件为控制平台,采用改进的广义开环响应控制(generalized open-loop response control,GORC)与PID控制相结合的控制算法,通过构建的具有丢包补偿的Smith预估器对丢包数据进行估计,得出补偿的估计值,并参与GORC滚动优化中,来实现对温度的实时监测与控制。以高温炉作为研究对象进行实验,结果表明所设计的无线温度控制系统不仅可以有效解决有线过程控制中存在的问题,而且可以解决无线通信过程中的丢包、迟滞等问题,具有良好的工业价值。

Abstract: To address the challenges of wiring difficulty, poor scalability, and high maintenance costs associated with wired control in industrial process control, this paper presents the design and development of a wireless temperature control system. The system utilizes the generalized open-loop response control-PID（GORC-PID） algorithm with packet loss compensation. The system adopts the Industrial WirelessHART standard protocol and deploys wireless hardware equipment to establish a wireless communication network, eliminating the need for wired communication. The MCGS configuration software serves as the control platform. The proposed approach combines the improved generalized open loop response control（GORC） with proportional integration differentiation（PID） control. A Smith predictor with packet loss compensation is constructed to estimate and compensate for packet loss data. The estimated value is then incorporated into the GORC rolling optimization process for real-time temperature monitoring and control. The system is validated using a high-temperature furnace as the research object. Experimental results demonstrate that the designed wireless temperature control system effectively mitigates packet loss and communication delays in wireless communication, showcasing its industrial value and applicability.

Key words: wireless communication, generalized open-loop response control(GORC), monitor and control generated system(MCGS), temperature control, packet loss compensation
