Fuzzy PID Control Of Room Temperature In Central Heating System And System Research

In this paper, the structure of Fuzzy adjustment by oneself is added into classical PID control structure based on theory of fuzzy and PID control and discussion is made deeply on control strategy of room temperature in central heating system. The main work includes design of fuzzy PID control system of the room temperature, such as the determination of the structure of controller, the choice and calculation of parameter, the sureness of membership function, the setting-up of fuzzy control table, etc.; On the meantime, having carried on the emulation test, fuzzy PID control succeeds in applied to this system. This system emulation is carried on in SIMULINK4.0 in MATALAB6.0. According to emulation result, we can find out the algorithm of fuzzy PID may improve the automatic control of the room temperature greatly. When the environment changes in the system, the system still has a good control effectiveness and express the stronger robustness.This paper combines together with the technology of computer, intellectual instrument and apparatus technology, sensor technology, modern electronic technology and communication technology. I designs and studies the software and hardware of the temperature monitor system of central heating and the monitor center. This system realizes the control and telecommunication in long range and is easy to manage and make the room temperature more comfortable; On the same time, it promotes users to conserve energy voluntarily and reaches the good energy-conserving result. This system has good economic benefits and social value.
