摘　　要：变风量空调系统的温湿度具有强耦合、迟延大等特点,常规的控制方法很难取得较好的控制效果。为解决上述问题,使用了一种约束预测控制算法。介绍了变风量空调系统的基本原理以及温湿度的耦合特性,给出了约束预测控制算法的推导过程,结合实际的模型进行仿真研究。仿真结果表明,所使用的算法可以快速跟踪温湿度设定值的变化,同时具有很强的抗干扰性。The temperature and humidity of VAV air conditioning system has the characteristics of strong coupling and large delay, so it is difficult to achieve good control effect by conventional control algorithms. In order to slove this problem, a constrained predictive control algorithm is used in this paper. The basic principle of VAV system and the coupled characteristics of temperature and humidity is introduced. The derivation process of constraint predictive control algorithm is given. Ccase studies are carried out with real model. Simulation results show that the algorithm used in this paper can quickly track the setpoint and has strong anti-interference.
