针对混合磁悬浮洁净传送装置无法兼顾零功率和抗偏载悬浮的问题,提出一种磁铁可动式混合磁悬浮系统,并设计了其零功率抗偏载控制策略。该系统中一个磁极固定,其他两个磁铁可绕悬浮圆盘中心轴线转动,通过调节气隙长度和磁铁转动角度克服偏载引起的扰动力和扰动力矩,从而实现零稳态电流和抗偏载悬浮。首先建立系统的线性变参数模型,分析该系统实现零功率水平悬浮需要满足的条件。零功率抗偏载控制策略在比例-微分控制器中引入电流和气隙偏差的积分反馈,并应用质心观测器反求磁体转动角度,求解方法分别采用雅可比逆变换解析求解和查表法内插取值两种方法。试验结果表明,该系统能够在偏载条件下保持零功率水平悬浮,应用雅可比的连续控制策略具有更好的纠偏特性,稳态时电流波动范围小。

Subloading-friction model with saturation of tangential contact stress

Friction 2023年第6期11卷 1107-1120页

作者： koichi HASHIGUCHI Masami UENO Kyushu University Fukuoka 819-0395Japan MSC Software Ltd. Tokyo 101-0054Japan University of the Ryukyus Okinawa 903-0213Japan

The incorporation of the saturation of the tangential contact stress with the increase of the normal contact stress is required for the analysis of the friction phenomenon of solids and structures subjected to a high normal contact stress,which cannot be described by the Coulomb friction condition,in which the tangential contact stress increases linearly with the increase of the normal contact *** this article,the subloading-friction model,which is capable of describing the smooth elastic-plastic transition,the static-kinetic transition,and the recovery of the static friction during the cease of sliding,is extended to describe this ***,some numerical examples are shown,and the validity of the present model will be verified by the simulation of the test data on the linear sliding of metals.
