Research on control and optimization of heavy-duty electromagnetic bearing of large-capacity energy storage flywheel

The rotor of a large-capacity flywheel energy storage system will cause energy loss due to air and mechanical resistance during high-speed operation, and the traditional PID control cannot take into account the system robustness under the large-sized and heavy-loaded rotor of the electromagnetic bearing system. This paper takes the heavy-duty electromagnetic bearing system as the research object, builds a fractional-order PID controller suitable for this system, and compares and analyses the operating characteristics of the electromagnetic bearing with that of the electromagnetic bearing under traditional PID control. The study shows that for the large-capacity energy storage flywheel heavy-duty electromagnetic bearing system, the use of fractional-order PID control technology can provide better control performance and anti-jamming ability, and thus ensure the stability and safety of the energy storage flywheel system.
