This invention proposes a dual-closed-loop control method for the dynamics of a magnetically levitated energy storage flywheel rotor based on LADRC (Laser-Adjustable Dynamic Control) to achieve stable levitation and dynamic control of the flywheel rotor. First, mathematical models of each degree of freedom of the flywheel rotor and a linearized model of the power amplifier-electromagnet coil are established in the magnetic bearing coordinate system. Then, the electromagnetic coupling terms, gyroscopic coupling terms, and imbalance terms in the flywheel rotor mathematical model are defined as external disturbances. Mathematical models of the flywheel rotor and power amplifier-electromagnet coil used for controller design are derived, and a second-order LADRC controller for the position loop and a first-order LADRC controller for the current loop are designed. Finally, the parameters of the position loop and current loop controllers are tuned using the pole placement method. Simulation results show that this dual-closed-loop control strategy can effectively decouple the degrees of freedom of the flywheel rotor under static and high-speed levitation conditions. Compared with PID control, it has better dynamic characteristics and stronger anti-disturbance capability. This is of great significance in ensuring the stable and reliable operation of the magnetically levitated energy storage flywheel rotor.
