Abstract:

The auto-disturbance rejection control (ADRC) system has the advantages of small overshoot and stability errors, fast response speeds, excellent anti-interference ability, and robustness. Aiming at the shortcomings of electromagnetic bearing proportion integration differentiation (PID) control in terms of immunity, this study investigated a 10 kWh flywheel energy storage system and designed a double closed-loop ADRC system. A control system of single-degree-of-freedom magnetic bearings was built with Simulink. A random noise signal was applied in different positions, and the control capability of ADRC was verified in active magnetic bearing (AMB) control applications with the mechanical error interference ignored. Moreover, the anti-interference abilities of the ADRC and PID control were compared. The anti-interference control system's response overshoot and steady-state error can be controlled within ±5%, indicating better anti-interference ability. The results provide a good reference for the design of the auto-disturbance rejection controller of the magnetic bearing.
