摘　　要：自抗扰控制超调小、响应快、稳定误差小,具有很好的抗扰能力和鲁棒性。本工作以10 kWh飞轮储能系统为研究对象,针对电磁轴承PID控制在抗扰能力方面的不足,设计了双闭环自抗扰控制系统。利用Simulink建立了单自由度磁轴承的双闭环自抗扰控制系统,通过在不同位置施加随机噪声信号,验证了自抗扰控制在磁轴承控制应用中的控制能力(忽略机械误差干扰),并对比分析了自抗扰控制和PID控制的抗扰能力,发现自抗扰控制系统的响应超调和稳态误差都可被控制在±5%以内,并且具有更好的抗扰能力,为电磁轴承自抗扰控制器的实现提供了设计参考。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.
