Abstract :
In this paper, we propose a design method for the uncertain rotor-sliding-bearing system. Firstly, the nonlinear terms in the nonlinear model of rotor-sliding -bearing system are regarded as energy bounded disturbance. Then, based on H∞ control theory, a novel parameter design method in term of LMI (Linear Matrix Inequality) is given for the rotor-sliding-bearing system. Finally, the simulation results show the effectiveness of the proposed design method.
