摘要:空调是人们生活中重要的电气设备，其舒适性提高了人们的生活质量，做好空调的控制具有极其重要的价值和意义，空调系统是一个大滞后、非线性、时变的复杂控制对象，参数多，结构复杂，很难确定其精确的数学模型。而模糊控制因无需建立被控对象的数学模型，抗干扰和鲁棒性强等特点，能很好的适应空调系统的控制。而变频空调由于其增加了变频器，能很好的运用于有负荷变化的空调系统。
本设计主要首先介绍了变频空调很适合于写字楼的空调系统，以及写字楼空调系统的原理，和变频空调器的简介。其次，通过对空调房间的数学模型进行了分析，建立被控对象即空调房间在定风量系统下的数学模型，表冷器及空调系统其他环节的数学模型，从而建立了整个空调房间控制回路的数学模型。再次，以空调房间的温度为研究对象，结合变频空调实际控制对象和工作特点，设计模糊控制器。最后，在MATLAB下建立了系统的模型，并在Siumulink环境下对系统进行了建模和仿真。仿真结果表明，模糊控制器比PID控制器控制性能好、具有较好的应用价值。

Abstract:Air conditioning is people life important electrical equipment，its comfort improved people's quality of life，to the control of the air conditioning is of great value and significance，and air conditioning system is a delay，nonlinear time-varying control object，complex，lots of parameters，the structure is complex，it is difficult to determine the accurate mathematical model. And the fuzzy control for instead of having to establish the mathematical model of the controlled objects，anti-jamming and strong robustness and other characteristics，can be very good to adapt to the control of the air conditioning system. And frequency conversion air conditioning because its increased frequency converter，can be a very good applied to load changes have air conditioning system.
This design main first introduced the frequency conversion air conditioning is very suitable for office air conditioning system，and the principle of office air conditioning system，and frequency conversion air conditioning implement the principle， structure，advantage. Second， through the mathematical model of the air conditioning room，the paper builds the controlled object that is in air conditioning room set of vav system mathematical model，table and air conditioning system other tanks in the link of mathematical model，so as to establish the control circuit of air conditioning room of the mathematical model. Again，to air conditioning the temperature of the room as the research object，combined with frequency conversion air conditioning actually control the object and the work characteristics，design of fuzzy controller. Finally，in MATLAB system was established under the model，and in Siumulink environment on the system modeling and simulation. The simulation results show that the fuzzy controller than PID controller good control performance，has a good application value.
Keywords: Fuzzy controller；Temperature control；The simulation；Air conditioning system
