摘　　要：依据切舍了高阶振动后得到的弹性转子系统低阶模型，提出一种有效克服振荡现象的新型Ｈ∞控制系统设计方法。通过求解互补灵敏度函数和调整函数在特定频域内的最小混合问题设计了Ｈ∞控制器。仿真结果表明，该方法以抑制系统振荡，保证系统鲁棒稳定性具有良好的效果。Based on a truncated low order model of flexible rotor system, this paper presents a new design method of H ∞ control systim for effectively surmouning the vibration phenomenon. The H ∞ controller is designed by sovling the minimum hybrid problen in the special frequency band of the sensitive function and the adjust function. Simulation results show that the method has good results for suppressing the vibration and has the robust stableness.
