基于降阶模型设计了一种次优输出反馈控制器，并将其应用于柔性转子轴承系统，以控制运行过程中出现的不稳定或轻阻尼振动。降阶模型是通过奇异摄动得到的分布参数系统的截断模态方程。通过在性能指标中引入溢出项的约束优化方法，避免了由于高频模态不可控引起的溢出效应而引起的失稳问题
A suboptimal output feedback controller is designed based on a reduced order model and applied to a flexible rotor bearing system in order to control the unstable or lightly damped vibrations occurring during operation. The reduced order model is a truncated modal equation of the distributed parameter system obtained through the singular perturbation. The instability problem arising from the spillover effects caused by the uncontrolled high frequency modes is prevented through the constrained optimization by incorporating the spillover term into the performance index
