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.
