针对目前变风量空调系统的模型都是用机理建模方法建立的情况，本论文用最小二乘法对机组部分进行系统辨识，建立了水阀?送风温度、变频风机?静压两个回路的模型，经验证比较接近实际系统；采用遗传算法对pid控制器的参数进行寻优，寻优结果令人满意；设计了变风量空调系统的lon控制网络，以此为实现手段，进行了定静压控制和最小总送风量控制，并在两种控制方式下，分析了各个回路的耦合情况、两种控制方式的稳定性和节能效果。 |
| 10. | The experiment ' s results show that the system is stable under the static pressure control and energy saving under the minimum total supply air volume control . although the terminal dampers ' s tuning time is prolonged under the minimum total supply air volume control , it can be reduced by adopting the appropriate sampling time when debugging the system . from all of this we can conclude thart the minimum total supply air volume control has a good application perspective
实验结果表明，定静压控制方式下系统较为稳定，最小总送风量控制比定静压更加节能，但它延长了末端阀位的调节时间，在系统调试时，我们可通过选择合适的采样时间来缩短阀门的调节过程，所以最小总送风量控制具有广阔的应用前景。 |
