Abstract :
The interference of torque component current of the motor to the radial position control of reluctance type bearingless motors is investigated. In order to cancel this interference, a decoupling control method has been proposed. With this method, machine parameters identification of radial force production is very important. It is shown that the radial force constants exhibit significant variations in accordance with the torque component current due to magnetic saturation. The parameter tuning of the decoupling compensator taking into account of the magnetic saturation is found to realize very stable operation in radial rotor position control
