基于模糊控制算法的温度控制系统的设计电气自动化专业摘要:以 AT89C2051 单片机为模糊控制器,结合温度传感变送器、A/D 转换器、LED 显示器、固态继电器等,组成一个基于模糊控制算法的温度控制系统
在此系统中,单片机将给定的温度与测量温度的相比较,得出偏差量
然后根据模糊控制算法得出控制量
采纳模拟的 PWM 控制方法,改变同一个周期中固态继电器的导通时间,从而调节电炉温度,达到控制的目的
从仿真结果可以看出,系统达到了预期目标

In such system, the single chip computer educe the control value based on the difference between the initialization and the measure value
Solid switch used as a analog PWM converter executor, change the close time in a decided periods, which aimed at control the temperature
Seen from the emulation r
