Abstract: A control system is provided for load sharing between a plurality of compressors (8, 34). The control system determines the actual coefficients of export flow for the compressors (CEF actual1 , CEF actual2 ), compares the actual coefficients of export flow with a common or individual coefficients of export flow setpoints (CEF SP) generated by one or more central controllers (48, 50), and then generates control signals for adjusting the operating points of the compressors in order to load balance the compressors.
