Abstract: Address to the complicacy and difficulty of wiring installation for wired process control in harsh industrial site environment, this paper develops a wireless temperature control system for high temperature heating furnace based on predictive functional control-proportion integration differentiation (PFC-PID). First, a wireless communication network based on WirelessHart protocol is built to replace the traditional wired network. The wireless network uses the monitor and control generated system (MCGS) configuration software as application platform to measure and analyze the industrial high-temperature heating furnace. Then the wireless temperature control system is developed by integrating the improved predictive functional control (PFC) with the traditional proportion integration differentiation (PID), to realize wireless monitoring and real-time control of the temperature of the heating furnace. The results of engineering implementation show that the designed control system can solve the problem of packet loss in the wireless communication process. It works with satisfied reliability, control accuracy and response speed required in industrial sites. The designed system can also solve the problems of low scalability and poor mobility of wired network effectively.

Key words: wireless network, predictive function control-proportion integration and differentiation (PFC-PID), monitor and control generated system (MCGS), temperature control, high temperature heating furnace
