摘要
运用拉格朗日方程,建立了磁悬浮动量轮系统径向平动的精确动力学模型,并以应用广泛的PD控制进行了运动分析。研究表明,两自由度径向磁轴承的径向平动方向存在一定的耦合运动,但藕合对运动妁影响甚微,实际控制中可以采用单自由度运动模型替代。这方面的研究对认识磁悬浮动量轮的运动特性有积极的作用。
The precise dynamic model of magnetic suspension momentum wheel's translation is proposed using La-grange's equations and the motion is analyzed with the widely used PD control method. The study indicates that two degree of freedom translation of magnetic bearing's radial direction is a coupled motion. The influence of coupled motion on the translation is small, so one-degree-of-freedom model can be used in in practical control.
