Because of the jamming signal is real-time changeable and control algorithm cannot timely tracking control flywheel rotor, this paper takes vehicle maglev flywheel battery as the research object. One kind of dual-model control strategy is developed based on the analysis of the vibration response impact of the flywheel battery control system. In view of the complex foundation vibration problems of electric vehicles, the nonlinear dynamic simulation model of vehicle maglev flywheel battery is solved. Through analyzing the nonlinear vibration response characteristics, one kind of dual-mode adaptive hybrid control strategy based onH∞control and unbalance displacement feed-forward compensation control is presented and a real-time switch controller is designed. The reliable hybrid control is implemented, and the stability in the process of real-time switch is solved. The results of this project can provide important basic theory support for the research of vehicle maglev flywheel battery control system.

“…A LQR scheme for vibration control in AMB system to reduce the unbalance vibrations is proposed by Arias, et al [5]. Moreover, iterative learning control is applied in the unbalance compensation for AMB system [6][7][8][9][10]. However, most of the existing methods to reduce the rotor unbalance vibrations in AMB system are based on the control system, which may to some extent influence the AMB system stability In this paper, a series of assault blocks are added to the rotor system.…”

In an active magnetic bearing (AMB) system, the rotor always rotates at extremely high speed which always accompany with huge vibrations and noises. Most of the former researches associated with reducing the rotor vibrations are mainly focused on the control methods of AMB. A new method of installing series of assault blocks in the rotor is proposed to reduce the rotor vibrations. Firstly, the dynamic models of rotor supported by AMB considering the influences of assault blocks are established. Then, both dynamic simulations with and without assault blocks are carried out separately using the real-time AMB support dynamic stiffness. The rotor vibration displacements are mainly analyzed. Finally, relevant experiments are made to verify the theoretical results. Both theoretical and experimental results validated the advantages of using assault blocks.

“…This particularly recommends them for use with non-linear systems, as methods based around linear models are naturally difficult to apply. Some of the non-linear systems they have been applied to include an injection moulding machine [93], magnetic bearings [94] and robot manipulators [95].…”
