基于LabVIEW的压缩机吸气压力模糊控制系统的设计

Study of LabVIEW-based Fuzzy Control System of Suction Pressure for Scroll Compressor

针对压缩机吸气压力耦合强、变化快且控制精度要求高的特点,在难以获得精确数学模型的情况下,利用模糊控制算法实现压缩机吸气压力的模糊控制,用LabVIEW的模糊控制器设计工具进行模糊控制器的设计。经实验证明,该控制系统具有良好的控制效果。

Aimed at the characteristics of the compressors such as strong coupling of pressure with other parameters, fast pressure change, and higher requirement of control accuracy, due to the difficulty in developing a precise mathematical model, a control sys- tem of compressors pressure was implemented by using fuzzy algorithm. The fuzzy controller was designed with the help of LabVIEW. It is verified by a real controlling that a satisfactory result can be achieved with fuzzy control.
