针对转子系统振动控制中的时滞现象，研究了时滞Ｈ∞控制。首先对线性转子系统设计时滞Ｈ∞控制器，并对可控挤压油膜阻尼器（ＣＳＦＤＢ）转子系统，用ＣＳＦＤＢ产生的非线性油膜力逼近线性转子系统的控制力，实现ＣＳＦＤＢ转子系统振动主动控制。数值仿真表明：时滞Ｈ∞控制器能较好地控制转子系统的不平衡响应，且较之无时滞Ｈ∞控制器使转子不平衡响应衰减更快。
Aiming at the time lag in the vibration control of rotor system, the time-delay H∞ control is studied. Firstly, a Hysteresis Controller (H∞) controller is designed for the linear rotor system, and the controllability of the linear rotor system is approximated by the nonlinear oil film force generated by the CSFDB in a controlled squeeze film damper (CSFDB) rotor system. control. The numerical simulation shows that the H ∞ controller can control the unbalance response of the rotor system better than the H ∞ controller without delay, which can attenuate the rotor unbalance response more quickly.
