Control Algorithm Analysis and Firmware Design in Tunnel Microwave Heating System

Applied in tunnel microwave heating system, single input single output fuzzy-self-setting PID algorithm has many restrictions because such system has close coupled property. Thus fuzzy decoupling algorithm is raised. Such decoupling algorithm can decrease or even eliminate the coupling of the variables in this system. The stability of the system can also be improved. Discussion over the developing of control firmware and upper-monitor interface is also included on the basis of the existing hardware platform. The efficiency and effectiveness of the designed control algorithm is mainly considered in this paper.
