Research on Structure Design and Control Algorithm of Maglev Precise Isolator

  • 摘要: 针对半主动隔振器存在精度不高、频带较窄等问题,设计了一种由永磁铁和电磁铁组成的混合磁悬浮隔振器结构,建立了动力学数学模型。根据控制精度和要求,提出一种改进型的双闭环控制策略,即采用改进型遗传算法对外环的自抗扰控制器(ADRC)参数进行优化,采用模糊神经网络对内环的PID控制器参数进行实时整定。通过MATLAB仿真比较,结果表明,采用优化控制算法后,系统超调量将小于1%,隔振器各参数稳定时间缩短了1.5 s左右。可见,改进后的控制算法具有较快的收敛速度,从而使混合磁悬浮隔振器具有更好的隔振性能。
