单自由度磁悬浮系统的状态反馈控制

为了使单自由度磁悬浮系统的转子稳定地悬浮在平衡位置，在建立系统状态空间模型的基础上，对系统引入状态反馈及误差积分的控制。通过仿真，系统的稳态误差为0，获得了较好的动态和稳态特性。这表明，引入误差积分控制的状态反馈闭环控制消除了系统稳态误差，保证了系统稳定、准确控制的要求。

States Feedback Control of Single- degree- freedom Magnetism Suspension System

In order to make the rotor of the single-degree-freedom magnetism suspension system suspend in the balanced position steadily, on the basis of setting up systematic state space model, the control of states feedback and integral of the error are introduced to the system. Through simulation, the systematic stable state error is 0. The system obtains better dynamic and stable state characteristic. This indicate, the closed-loop control of states feedback and integral of the error which are introduced to the system,dispels the systematic stable state error, and ensures the request that the system is controlled steadily and accurately.
