| Abstract |
The use of active magnetic bearings (AMB) is increasing in high-speed applications, because their lowfriction operation allows higher rotational speeds than the traditional bearings. The inherent instabilityand complexity of the AMB rotor system with high nonlinearities pose challenges to the controller design.This leads to a problem of robust design. Robustness of LQG and loop-shaping H¥ controllersis compared with the help of the evolutionary algorithm both theoretically and based on experimentalmeasurements. |
