在制冷空调系统中采用电子膨胀阀（ＥＸＶ）代替传统的热力膨胀阀后，为各种调节控制技术的应用提供了广阔的前景．作者介绍了模糊控制器的设计及在制冷空调系统中的应用前景，并通过Ｍａｔｌａｂ工具包中的Ｓｉｍｕｌｉｎｋ软件进行模拟仿真，验证了模糊控制器的控制特性．
The use of electronic expansion valve (EXV) in the refrigeration and air-conditioning system instead of the traditional thermal expansion valve, provides a wide range of applications for the application of various regulation and control technology. The author introduces the design of fuzzy controller and its application prospects in the refrigeration and air conditioning system, and simulates it through the Simulink software in the Matlab toolkit to verify the control characteristics of the fuzzy controller.
