自整定模糊控制器在变风量空调温度控制中的应用研究

VAV air-conditioning Temperature Control

针对变风量空调的结构和运行原理,设计了变风量空调的监控系统。在监控系统中利用组态软件和VC实现了常规模糊控制器和参数自整定模糊控制器的设计。分别利用两种不同控制器进行了室内环境温度的控制,并进行了超调量、调整时间和稳态误差等控制性能的比较。结果表明自整定模糊控制器根据温度偏差的大小自动调整其论域,从而提高了控制精度,改善了控制性能。

VAV air-conditioning system has the characters of nonlinear and non-stationary under the influence of many factors, so it is hard to tune the parameters of the fuzzy control system. According to the structure and operation principle of VAV air-condi- tioning system, the monitoring system has been developed. The conventional fuzzy control algorithm, temperature parameters self-tuning fuzzy control algorithm were researched in the system. The results of experiments carried out indicate that the self-tuning parameters fuzzy control algorithm can improve the performance of the fuzzy controller entirely.
