摘要:空調是人們生活中重要的電氣設備，其舒適性提高了人們的生活質量，做好空調的控制具有極其重要的價值和意義，空調系統是一個大滯后、非線性、時變的復雜控制對象，參數多，結構復雜，很難確定其精確的數學模型。而模糊控制因無需建立被控對象的數學模型，抗干擾和魯棒性強等特點，能很好的適應空調系統的控制。而變頻空調由于其增加了變頻器，能很好的運用于有負荷變化的空調系統。

　　　本設計主要首先介紹了變頻空調很適合于寫字樓的空調系統，以及寫字樓空調系統的原理，和變頻空調器的簡介。其次，通過對空調房間的數學模型進行了分析，建立被控對象即空調房間在定風量系統下的數學模型，表冷器及空調系統其他環節的數學模型，從而建立了整個空調房間控制回路的數學模型。再次，以空調房間的溫度為研究對象，結合變頻空調實際控制對象和工作特點，設計模糊控制器。最后，在MATLAB下建立了系統的模型，并在Siumulink環境下對系統進行了建模和仿真。仿真結果表明，模糊控制器比PID控制器控制性能好、具有較好的應用價值。

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.
