Design and Implementation of Cascade Fuzzy Controller For Secondary Pipe Network Of Heat Exchange Station

In view of problems of obtaining and tracking given value of the supply water temperature of secondary network in central heating system, a fuzzy control strategy composed of fuzzy control and fuzzy parameter self-tuning PID in series was proposed. For a specific project, a monitoring and control system formed of wired and wireless network was built to meet the overall monitoring requirement of system. Total scheme of the network structure, control strategies, as well as system configuration and realization methods of the related process were designed. Meanwhile, Simulation experiments on the MATLAB/SIMULINK software platform of the cascade fuzzy controller were also designed in detail. In order to improve reliability and real-time performance of the control, the cascade fuzzy controller was realized on Siemens S7-200PLC. The simulation results and practical effect both show that the cascade fuzzy controller has good dynamic performance and robustness. Design of the monitoring and control system based on control network comprehensively improves the human-computer interaction ability, as well as management and automatic control level.
