ABSTRACT:
A method is provided for controlling operation of a compressor having an inlet and an outlet, a variable geometry diffuser communicated with the outlet, and inlet guide vanes communicated with the inlet, wherein the method includes the steps of: determining a loading parameter indicative of onset of surge; and independently controlling the inlet guide vanes and the variable geometry diffuser based upon the loading parameter so as to allow increase in efficiency and stable operation of the compressor.
