分户热计量供热系统中的分户温度模糊控制

The FUZZY control of room temperature in a heating system designed for household heat measurement

房间温度控制是典型的时变迟滞系统,用常规PID控制方式很难实现有效控制,而常规FUZZY控制因其稳态性能不佳,又不能满足某些分户热计量供热系统中的分户智能温控装置对室内热环境实现智能控制的稳态温差不超过±1℃的要求。笔者设计出了一种行为自校正模糊控制器,应用到某分户热计量供热系统中的分户智能温控装置中,通过MATLAB仿真结果表明:该行为自校正模糊控制器的性能优于常规FUZZY控制器和PID控制器。

It is difficult to perform any effective control when a conventional PID control method is applied to a room temperature system with time varying and hysteresis characteristics.It is also difflcult for the conventional fuzzy control to realize its function with a steady state temperature error of no less than ±1℃.This paper deals with the design of a fuzzy controller with self-correcting fuzzy control rules applied to a room temperature control system.The result of the MATLAB simulation has shown that the self-correcting fuzzy controller is superior to the conventional fuzzy controller and PID controller.
