  Compressors are of particular importance due to their wide application in various industries for compression and gas transmission. Due to the increasing use of compressors in the industry, it is imperative to determine a mathematical model for the compressor to design a control system, analyze it and its simulating in corresponding computer software like MATLAB. In recent years, intelligent modeling such as neural and fuzzy networks due to the more realistic performance of these models has been considered by researchers. Its types have been used for modeling. Intelligent methods have a high ability to stablish a relation between input and output data. On the other hand, in compressors surge phenomenon is a challenging case which occurs very quickly and will cause damage to the compressor and the production process. This phenomenon is defined as an instability in the operation of the compressor. Surge control expands the operating range of the compressor and exhibit the occurrence of this phenomenon. This article reviews modeling, surge phenomenon, and types of active and inactive surge control. For modeling, from the Moore–Greitzer’s model to intelligent models, it has been studied that according to the obtained results, it can be said that the Moore–Greitzer’s model has more errors over time than intelligent models and is a suitable model. Not from the compressor. Next, the control of the surge phenomenon in the compressor is checked by active and passive methods. The compressor's control in the active mode does not require a compressor performance curve. Still, in the passive method, it controls the compressor by using the performance curve and creating a safety margin from the surge line. So as not to enter the surge phenomenon. This makes active control performance more efficient than passive control. Manuscript profile
