摘　　要：Surge and rotating stall occurring in a centrifugal compressor system are investigated by using a phaseportrait reconstruction method. From experimentally measured time series of data, the method clari-fied the cyclic behavior of surge. For rotating stall, there still remain problems in the phase portraitdue to the chaotic behavior. However, the results obtained by the present method are able to providenew insights to the modelings for surge and rotating stall.
