摘要

本文介绍了一种具有相变蓄热的太阳能新风供暖系统作为一种环保节能方法,并根据热力学定律推导了空调房间的数学模型。针对新风温度的控制问题,提出了自整定参数模糊PID控制器,以抑制因时间延迟问题和参数变化引起的扰动,通过调节流量来控制新风温度。通过仿真和实验验证了所提出的控制器与传统PID控制器相比具有更高的控制精度、更快的响应速度和更强的鲁棒性。

Modeling and optimized control algorithm for a solar fresh air heating system
A solar fresh air heating system with phase change thermal storage was introduced in this paper as an environmental protection energy saving method, and the mathematical model of the air conditioning room was derived based on law of thermodynamics. The fresh air temperature control problem was also addressed, and self-tuning parameter fuzzy PID controller was proposed for disturbance rejection due to the time delay problem and parameter variations, which was designed to regulate the flow rate to control the fresh air temperature. The controller presented is then validated, through simulation and experiment, to provide superior control performance with higher control accuracy, faster response and stronger robustness to a conventional PID controller.
