转子系统鲁棒H^∞控制

Robust H ∞ Control of Rotor System with Structural Uncertainty

针对转子振动控制中，模型转子系统与实际转子系统间的误差及模型转子系统中存在的结构不确定性，研究了鲁棒Ｈ∞控制．对同时具有刚度和质量不确定性的转子系统，设计了鲁棒Ｈ∞控制器．仿真结果表明：文中的鲁棒Ｈ∞控制器能有效地控制转子系统的不平衡响应，使转子系统在共振区的不平衡响应峰值减少７０％以上，且求解简单．

Based on the H ∞ control theory, a robust H ∞ controller was found out for rotor systems with uncertainty of mass and stiffness. For the model rotor system, simulation shows that robust H ∞ controller can rejected the imbalance response effectively.
