摘要
介绍了单电磁铁悬浮系统的动态模型,并以该动态模型为基础,采用状态空间法设计了以电压作为输入控制量的闭环控制器,并且运用Matlab进行了相应的仿真。该方法简单实用,控制参数无需经验试凑。试验结果表明,系统控制效果良好,有一定的实用价值。
Because of the complicated nonlinearity of magnetic levitation system （SMLS）, the limitations of methods based on the theory of linear systems were outstanding. In this passage, the dynamic mathematic model of SMLS was introduced, and a voltage closed loop controller was designed through the state - space method based on it. And it was simulated by Matlab. The control arithmetic was simple and useful, and the control parameters need no trial and error by experience. Experiment result demonstrated that the control effect of the system was satisfied.
