Abstract

Vertical rotating devices may cause large amplitude vibration or even lose stability during low-speed operation. This paper discusses the control approaches of a low-speed vertical rotor orientation system based on the electromagnetic levitation. In the paper, according to the gyro mechanics principle, the nonlinear dynamic equations of the vertical rotor system are established and the kinetic characteristics of the system in the gravitational field are analyzed. Considering the uncertainties of the system, a position control strategy used for the vertical rotor orientation system is presented based on the gyroscope effect. Finally, the simulation of the control system and experiment system are carried out and set up to verify the feasibility and effectiveness of the control method. Results show that the presented control approach is able to achieve a stable positioning control for the spinning rotor.
