基于预测优化控制的变风量空调系统控制策略的研究

The Control Strategy Research Based on the Prediction Optimization Control of Variable Air Volume System

基于变风量空调送风系统的运行特点,建立了风量预测优化控制模型,设计了变风量空调前馈-反馈综合控制系统。实验结果表明:基于预测优化控制的空调系统运行稳定,各个空调小室的温度都能够稳定于设定温度所要求的精度范围内;各个控制环节的耦合度很小,能够实现独立控制调节,系统运行灵活、稳定。

Air volume prediction control model is established based on the operation characteristic of vari- able air volume system, and the feed-forward and feedback integrated control system is designed. The experi- ment result shows air conditioning system is running stability, and the temperature of each room satisfies accu- racy requirement of the setting temperature; different segments of control coupling is small. And it can be ad- justed to achieve independence, stable running of the system.
