Paper Abstract

The paper applies Selective Modal Analysis (SMA) to a simple linearized model of the dynamics of a multistage axial flow compressor-throttle system. The technique allows quantification of the degree of participation of each system variable in system modes. This feature allows determination of the participation of each stage in an overall compression system mode. The main application is to determine the stage(s) most involved in a mode of instability, with the associated implications for control design.
