摘　　要：以小型PLC锅炉液位控制为例,介绍了PLC实现锅炉液位模糊自适应PID控制的方法,并总结了PLC实现模糊自适应PID程序设计的关键技术。实验结果表明,无论是动态指标,还是静态指标,都比常规PID控制优越,为应用PLC实现复杂控制算法提供了程序设计方法。Take the boiler＇ s liquid level control based on small PLC as an example, the realization method of boiler＇s liquid level fuzzy self-adaptive PID control is introduced and the key technology of fuzzy self-adaptive PID program design by PLC is summarized. Through the experimental results, dynamic index and static index are superior to the normal PID. The method of program design is provided to realize the complex control algorithm based-on PLC.
