Simulation of Indoor Temperature Control Using Self- adjusting Method in VAV Air Conditioning System

针对变风量空调系统控制的复杂过程,建立了空调房间在VAV空调方式下的数学模型,并将可变论域参数自调整Fuzzy PID控制方法应用于室温控制中;利用MatLab软件的仿真模块,对控制系统进行仿真。结果表明,可变论域参数自调整Fuzzy PID控制方法动态响应速度快,超调量小,具有较强的鲁棒性,对理论研究和工程实践具有一定的指导意义。

Based on the complex control process in VAV system, the mathematical model of the room in the way of VAV is gained, and the changeable discourse Fuzzy PID control method is applied to control the indoor temperature. The control system is simulated by using the software of MatLab. The result shows that the changeable discourse Fuzzy PID control method has fast response, small overshoot, and strong robust. This paper has practical guiding effect in the theory research and engineering practice.
