AI Technical Summary
In existing technologies, energy storage flywheels and anti-roll gyroscopes are usually designed as independent systems, making it difficult to achieve deep integration. They also suffer from problems such as high frictional losses, limited rotational speed, and unstable anti-roll torque output, making it impossible to achieve synergy between high-speed energy storage and large-inertia anti-roll within the same flywheel unit.
The magnetic levitation flywheel system integrates a magnetic levitation support structure, a precession actuator, and a bidirectional energy exchange interface within the same flywheel unit. It utilizes precession control to achieve anti-roll torque output and coordinates flywheel speed and precession control through a coordinating controller to achieve synergistic unity of anti-roll and energy storage.
It achieves the ability to maintain anti-roll torque output under energy storage operation with variable flywheel speed, reduces mechanical friction, improves system flexibility and stability, enables coordinated operation in complex sea conditions, and enhances ship navigation stability and energy utilization efficiency.
