Adaptive PID control for flexible rotor supported by active magnetic bearings based on single neuron with varying learning rates

  • 摘要: 为同时保证磁悬浮轴承柔性转子系统所需的低频和高频特性,在一般单神经元PID(proportion integration differentiation)控制的基础上,将转速信号引入磁悬浮轴承数字控制器,在不同转速段选择不同的学习速率以调节控制参数得到合适的磁悬浮轴承的刚度和阻尼.试验结果表明,变学习速率单神经元自适应PID控制能够明显减小转子在各阶临界转速时的振幅,有助于磁悬浮轴承柔性转子系统的安全稳定运行.
