Design of Fuzzy PID Temperature Control System
Xi'an Traffic Engineering Institute
Temperature plays an important role in daily life, industry production and scientific experimentation. However, because of the multi characteristics of nonlinearity, large lag, and time-varying of control objects, there will be great difficulties in establishing accurate mathematical models with mathematical methods. In order to achieve well controlling effects, this paper proposes a mature controlling system. This system combines PID algorithm and fuzzy control to design a fuzzy PID intelligent controller, which could process complex data and complex systems simultaneously. The high flexibility of fuzzy control and the high precision of PID control of this system could solve the influence of large inertia and interference of the temperature control system. This design will adopt the STC89C52 MCU as the main control core. Meanwhile, the fuzzy PID controller are combined with fuzzy control and PID control to control the temperature. In this paper, we first introduce the hardware composition of PID temperature control system. Secondly, we use proteus to build the general circuit diagram, and then use KEIL software to program again. Finally, we simulate the system and analyze the simulation results by the simulink module in MATLAB, and finally achieve the expected results.
