Stability of Rotor Systems: A Complex Modelling Approach

Wolfhard Kliem, Christian Pommer, Jakob Stoustrup

    Research output: Book/ReportReportResearchpeer-review


    A large class of rotor systems can be modelled by a complex matrix differential equation of secondorder. The angular velocity of the rotor plays the role of a parameter. We apply the Lyapunov matrix equation in a complex setting and prove two new stability results which are compared with the results of the classical approach using Rayleighquotients. Several rotor systems are tested: a simple Laval rotor, a Laval rotor with additional elasticity and damping in thr bearings, and a number of rotor systems with complex symmetric 4x4 randomly generated matrices.
