Bifurcations of Control Systems with Application to Flutter

Abstract

The concept of a control bifurcation grew out of an AFOSR PRET project to study the robust stabilization of axial flow compressors. Several versions of the Moore Greitzer compressor model were used in this study. McCaughan had studied the classical bifurcations that were present in the three dimensional Moore Greitzer equations(MG3) as the throttle and other parameters were varied. Liaw and Abed considered the throttle and other parameters as a control and developed feedback laws to change the criticality of the primary Hopf bifurcation in MG4.
