摘　　要：控制系统产生振荡是VAV空调系统的最大问题之一。建立了空调室及控制器的动态特性模型 ,开发了计算机仿真系统 ,并对VAV空调系统进行了仿真。仿真结果表明控制系统的稳定范围受控制参数和系统参数的影响。得到的极限参数ku,ωuVAV control system hunting is one of the most severe problems of VAV air conditioning systems. Develops dynamic models to the air conditioned room and controller, exploits a set of computer simulation software. The simulation results show that the stability region of VAV control system is influenced by the control and system parameters. The ultimate parameter model could be used for guidance in engineering practice.
