传统磁轴承三电平调制策略在数字控制系统中存在控制延迟问题,影响电流纹波抑制效果。针对上述问题,提出一种基于混合逻辑动态模型预测控制器的磁轴承三电平调制策略。基于混杂系统理论,建立混合逻辑动态模型,统一表征出驱动电路充电、放电和续流工作模态,实现三电平调制;结合模型预测控制理论,将所建立的混合逻辑动态模型作为预测模型,预测磁轴承的控制电流,实现对控制延迟的补偿,并将预测控制电流送入到代价函数中,得出驱动电路的最优控制信号;基于所提调制策略构建了磁轴承控制系统,并与传统调制策略进行对比。仿真结果表明:在轻载扰动工况下,所提调制策略相比于传统三电平滞环调制策略与传统三电平脉冲宽度调制(pulse width modulation,PWM)策略,电流纹波分别降低了49.90%和49.87%;在中载扰动工况下,所提调制策略相比于传统三电平滞环调制策略与传统三电平PWM策略,电流纹波分别降低了49.99%和49.84%;在重载扰动工况下,所提调制策略相比于传统三电平滞环调制策略与传统三电平PWM策略,电流纹波分别降低了50.08%和49.77%。在三电平调制机制的基础上,所提调制策略能够有效补偿一个采样周期的控制延迟,达到降低电流纹波的效果。

以交叉沟槽型织构动压轴承为研究对象,以量纲一的沟槽宽度Λ、沟槽深度Γ以及沟槽间夹角α为交叉沟槽型织构参数,并基于Fluent软件对织构几何特征方程、黏温方程、完全空化控制方程、静特性参数方程进行模型验证,在考虑流体润滑中存在黏温-空化耦合关系的基础上分析Λ,Γ,α对织构轴承润滑性能的影响。结果表明:相较于定温工况,黏温效应会增大润滑流体空化体积分数,进一步诱导空化效应;交叉沟槽型织构的参数与流体动压润滑性能之间存在耦合关系,α为30°,Λ为0.5,Γ为0.02时,织构轴承润滑性能最好;Λ为0.5,Γ为0.02时,织构轴承的端泄流量大于无织构轴承,增大α可以增大织构轴承的端泄流量。
