摘　　要：研究了含有参数不确定性的以电磁轴承支撑挠性转子的鲁棒H∞控制器,折衷考虑转子系统的外激励干扰衰减和转子系统参数摄动,将参数摄动转化为外扰动输入,建立了以电磁轴承支撑挠性转子H∞标准模型。数值仿真表明:建立的H∞标准模型合理;采用H∞控制设计的电磁轴承主动控制系统,能够有效的抑制参数摄动引起的扰动和持续的外激励干扰。To research on robust H∞ control of the flexible rotor with the coefficient uncertainty supported by active magnetic bearings (AMBs), trading off between the attenuation of outside inspiration and the uncertainty of this AMBs' system is made by translating the latter into the outside disturbance. The standard H∞ former of flexible rotor is supported by AMBs. Simulation result shows that the H∞ former for the flexible rotor system of AMBs is reasonable, and the disturbance due to coefficient uncertainty and continuous external inspiration can be restrained in the active control system design by robust H∞ method.
