Abstract

A jet turbine engine compressor disk is modeled as a rotationally periodic structure. An adaptive parameter estimator was used to eliminate the inter-blade coupling forces. The individual blade vibrations were then suppressed using a positive position feedback method. The resulting control law was tested on a simulated four and eight bladed system.
