Abstract

In this paper, we address the problem of the stability analysis of the rotor-sliding-bearing system. Firstly, we regard the nonlinear terms in the nonlinear model of rotor-sliding-bearing system as energy bounded disturbance. Then, based on H_infin control theory, a novel stability analysis method in term of LMI (linear matrix inequality) is proposed for the rotor-sliding-bearing system. Finally, the simulation results are provided to show the effectiveness of the proposed analysis method.
