  • METHOD AND SYSTEM FOR CONTROLLING A VARIABLE-GEOMETRY COMPRESSOR
    Publication number: 20200063651
    Abstract: A method for controlling a VG mechanism for a compressor employs a predefined VG setpoint map comprising optimum VG setpoints for the VG mechanism based on at least one predefined optimization criterion. The VG mechanism has at least three different setpoints ranging between a minimum flow area setpoint and a maximum flow area setpoint. A location of an operating point of the compressor on its compressor map is determined. Based on the location of the operating point, the VG setpoint map is consulted and an optimum VG setpoint is determined. A predictive scheme can be included for accounting for time lag of the VG mechanism's response.
