“…Examples of challenging topics are speed regulation [ 50 ], robust stabilization [ 51 ], and surge avoiding [ 52 , 53 , 54 , 55 , 56 ]. In addition to these topics, FDI systems on centrifugal compressors have also proven to be a very useful tool [ 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 ]. Time series analysis is combined with neural network in [ 57 ] to perform a correct fault diagnosis on centrifugal compressors.…”
