摘要
磁悬浮轴承是一种新型无接触轴承,文章以带有永磁卸载轴承的轴向电磁磁悬浮轴承为研究对象。由于对永磁力的线性化产生一定误差,为保证稳定悬浮本文利用结构奇异值μ综合法设计了电磁轴承μ控制系统,并将永磁力误差作为不确定量引入。最后通过仿真证明控制器满足工作要求。
Magnetic suspension bearing is a new non-contact bearings technology. This paper focused on an axial active magnetic bearing with a permanent unloading magnet, and designed an active magnetic hearing μ controlling system with μ comprehensive method. Because of the permanent magnet linear force with some errors, in order to ensure stable suspension, a Ix-Synthesis control system is needed, as well as quoted the permonent magnet error as an uncertain quantity. Finally, the simulation proved the controller can meet the job requirements.
