The Use of Signal Analysis and Identification Methods for Correction of Unbalance Computations

Abstract

This paper describes a scheme for the correction of mass unbalance computations for the effect of torque disturbances. A general approach is dealt with, showing how to assess the disturbance of variables in monitoring schemes. Also described is a method to rank the disturbances according to their importance. The scheme makes use of conditioned signals, and mainly the multiple coherence function. An example dealing with a combustion engine test stand is given.
