摘 要: 在建立电磁轴承数学模型的基础上,设计了基于H∞控制理论的鲁棒控制器,研究起动时系统的响应、受扰情况及控制电流和转子位移之间的关系,讨论起动性能的影响因素.实验表明,H∞控制器作用下的电磁轴承系统具有良好的起动特性、鲁棒性和干扰抑制效果. Based on math model of active magnetic bearing and the theory of H_∞ control, the robust controller was designed. Initial response and disturbance suppression effect were studied. The relationship between control current and displacement of the rotor was analyzed. The influence factor worked on initial performance was discussed. The results show the H_∞ controller was able to ensure the system to have good starting characteristics, strong robustness, and satisfying disturbance suppression effect.
