摘要

介绍了一种集太阳能集热器和潜热蓄热系统的新风系统。它不仅可以保持室内空气的良好质量，还可以为房间提供部分热量。此外，它具有节能的优点，当系统与空调系统配合使用时，不会造成额外的空调负荷。由于系统的非线性和滞后性，很难建立精确的数学模型。因此，可以采用模糊逻辑控制算法来实现系统的新风温度控制。考虑到PID控制器具有使系统稳态误差最小的良好性能，本文设计了自整定参数模糊PID控制器。实验结果表明，自整定参数模糊PID控制器在新风温度控制系统中具有优于传统PID控制器的控制性能。

Self-tuning-parameter fuzzy PID control in fresh air system

A fresh air system with solar collectors and LHTS (Latent Heat Thermal Storage) was presented in this paper. It can not only keep indoor air good quality, but also supply part of heat for rooms. In addition, it has an advantage of energy-efficient and will not cause extra air-conditioning load when the system is used in conjunction with air-conditioning system. For the nonlinearity and hysteresis of the system, it is difficult to found precise mathematical model. Consequently, fuzzy logic control algorithm can be used to realize the fresh air temperature control in the system. In consideration of the PID controllers' good performance to minimize the steady state error of the system, a self-tuning-parameter fuzzy PID controller was designed in this paper. Result from experiments shows that the self-tuning-parameter fuzzy PID controller has superior control performance in fresh air temperature control system compared to a conventional PID controller.
