摘要
从增强悬浮稳定性的目的出发 ,在对磁悬浮控制系统进行数学建模的基础上 ,提出了采用气隙变化、磁铁垂向位移变化速度和磁铁垂向位移变化加速度作为反馈控制量的具体控制方法 ,并在多体动力学软件SIMPACK中建立真实模型时考虑现实控制系统中轨道的激扰和控制器本身的干扰 ,最后通过对仿真结果的分析 ,得到控制的各项性能表现 。
Based on the mathematics model of EMS control system , a specific method to realize suspension control with using airgap deviation , velocity of magnetic vertical position deviation and absolute acceleration of magnetic vertical position deviation as feedback variables is prompted to improve the suspension stability .Think of rail excitation and disturbance of controller when make models in SIMPACK .At last,all the control performance characteristics are gained through analysis of simulation curves , and the feasibility of this control method is verified .
