本文提出了一种具有自由边缘的薄钢矩形板（长：800mm，宽：600mm，厚：0.3mm）的电磁悬浮控制方法。为了对钢板弹性振动的抑制进行基础研究，在钢板的两个相对边缘处采用塑料梁进行加固。该板由五个电磁执行器的吸引力以非接触方式支撑，这些电磁执行器由五个间隙传感器的反馈信号控制，以稳定悬浮行为。本研究应用了最优控制理论和次优控制理论。为了验证这些方法的有效性，进行了应用最优数字控制理论的实验。结果证实这些控制方法对于悬浮板非常有效，并且进一步观察到通过应用次优控制方法抑制了残余振动模式的溢出。
In this paper, a method of electromagnetic levitation control of a thin steel rectangular plate (length : 800mm, width : 600mm, thickness : 0.3mm) with free edges is prerented. To carry out fundamental investigation of the restraint of elastic vibration of the plate, the steel plate is reinforced by plastic beams at two opposite edges. This plate is supported in a contactless manner by attractive forces of five electromagnetic actuators which are controlled by feedback signals from five gap sensors to stabilize the levitation behavior. The optimal control theory and the suboptimal control theory are applied in this study. To verify the usefulness of these methods, experiments in which the optimal digital control theory was applied were performed. As a result, it was confirmed that these control methods were very effective in levitating the plate, and it was further observed that the spillover of residual vibration modes was restrained by applying the suboptimal control method.
