针对建筑电气设备自适应模糊PID一直存在能耗过大的问题。提出基于自适应模糊PID节能控制方法,将建筑电气设备系统的温度波动和温度波动率,作为自适应模糊PID控制系统的输入项,将PID控制系统的三个参数波动量作为输出项,构成双输入三输出控制结构。依据自适应模糊PID调节规律表中的信息,调整电气设备模糊逻辑系统的参数。通过运算自适应模糊PID节能控制函数,获取最佳温度值,实现节能目标。实验结果表明:自适应模糊PID节能控制系统起动电流低、噪声小、控制精度高;在一般扰动和大扰动下系统响应波动较小、适应能力更强、动态性能高;该算法下建筑电气设备单耗节能率为88.69%,节能效果显著。

Aimed at building electrical equipment adaptive fuzzy PID always has the problem of energy consumption is too large. Based on adaptive fuzzy PID energy-saving control method is put forward,the building electrical equipment temperature fluctuations and volatility in the system,as an adaptive fuzzy PID control system of the entry,the three parameters of PID control system fluctuation quantity as output item,constitute three output control structure with two inputs. According to the information in the adaptive fuzzy PID control rule table,adjust the parameters of the fuzzy logic system,electrical equipment evaluation by adaptive fuzzy PID energy-saving control functions,to obtain the best value,realize the goal of energy saving. The experimental results show that the adaptive fuzzy PID low starting current,low noise,energy saving control system control accuracy is high. Under general disturbance and large disturbance system response to a less volatile and more resilient,high dynamic performance;The algorithm under construction electrical equipment unit consumption and energy saving rate is 88. 69%,energysaving effect is remarkable.
