基于自适应模糊PID控制器的温度控制系统

Temperature Control System Based on Self-adaptive Fuzzy PID Controller

针对温度控制系统非线性、大滞后、时变性等特征和对温度控制的要求,采用了自适应模糊PID控制器来实现温度控制,给出了C8051F020Soc单片机控制实现的具体方案。仿真和实验结果表明了该系统的控制效果优于常规PID控制器,满足温度控制系统实时性和精度的要求。

According to the characteristics of nonlinearity, large delay and time-varying and the requirements for temperature control, the self-adaptive fuzzy PID controller was adopted to realize temperature control. Moreover, its implementation with C8051F020 Soc MCU was also given. The simulation and experimental results show that this self-adaptive fuzzy PID controller is much better than the conventional PID controller, and can meet the requirements of real-time and precision for temperature control system.
