    摘要: Method for controlling the pressure and temperature of a fluid, in particular helium, in a series of cryogenic compressors, comprising the steps of: detecting an actual rotational speed for each compressor(V
    1 , V
    2 , V
    3 , V
    4 ), detecting an actual inlet pressure(p
    ist ), and also an actual inlet temperature (T
    ist ) at the entry of the furthest-upstream first compressor (V
    1 ) of the series, providing a maximum speed (n
    i ,
    max ) for each compressor (V
    1 , V
    2 , V
    3 , V
    4 ) of the series, and also a setpoint inlet pressure (p
    soll ) for the first compressor (V
    1 ) of the series, determining a speed index (D
    i ) for each compressor (V
    1 , V
    2 , V
    3 , V
    4 ) from the maximum speed (n
    i ,
    max ) and the actual speed (n
    i ) of each compressor (V
    1 , V
    2 , V
    3 , V
    4 ), determining a proportional value (prop) from the deviation of the actual inlet pressure from the setpoint inlet pressure (p
    ist , p
    soll ), determining a priority value (PW) from the smaller of the two values; proportional value (prop) and the smallest speed index (D
    i ) of all the compressors (V

    3 soll , n
    4 soll ) for each compressor (V
    1 , V

    ist ) of the first compressor (V
    1 ), to the ascertained setpoint inlet temperature (T
