Gimballing Control and Its Implementation for a Magnetically Suspended Flywheel

The idea of utilizing the gyroscopic effects in rotor dynamics level was proposed to improve the precision of gimbaling control of a magnetically suspended flywheel(MSFW). The dynamics couplings of a rotor are the main problems of tracking control. A feed forward matrix was proposed. Implementations of gimballing control were discussed. Angular displacement stiffness will degrade the precision of gimballing control, and additional currents were added to coils to compensate the disturbance. The experimental results show that adopting the proposed methods, the tested MSFW can generate a torque of 1.92Nm.
