The Environment Monitoring System of Refuge Cabin and its Simulation Based on Fuzzy-PID Algorithm

Abstract

In order to improve people's chances of survival, Multifunctional fire refuge compartment, a kind of emergency equipment, was invented when a high-rise building breaking out of fire. One key component of it is the environmental monitoring system of refuge cabin. Meanwhile, to ensure that the refuge chamber system can respond quickly and be stable operation, it takes an kind of intelligent control technology which combined with traditional PID control(Proportion、Integration、Differentiation)and fuzzy control technology, namely fuzzy PID control to regulate. In this paper, combined with the fuzzy control technology, we discuss the fuzzy self-tuning PID control method of refuge cabin environment monitoring system. Try to make digital processing of control system by MCU(Micro Control Unit), we use the Simulink and Fuzzy toolbox in MATLAB to simulate the refuge compartment cooling system which using the fuzzy PID control method and compare with the conventional PID control. The result shows that Fuzzy-PID control method reduces the overshoot of the system, shortens the settling time, decreases steady-state deviation, improves the static and dynamic characteristics of the system effectively. Finally, it can enhance the reliability and adaptability of the system.
