摘要

高分辨率薄膜应变传感器已成功集成到仪器悬架原型中，并用于操作实验磁盘驱动器。根据实验数据得到了真实的植物模型和扰动模型。然后利用多速率、标称H2控制合成来研究闭环振动抑制。仿真结果表明，辅助的高分辨率、高速率应变传感改善了跟踪性能。

Enhanced vibration suppression in HDDs using instrumented suspensions

High resolution thin film strains sensors have been successfully integrated into instrumented suspension prototypes, and utilized in an operating experimental disk drive. Realistic plant and disturbance models were obtained from experimental data. Multi-rate, nominal H2 control synthesis was then utilized to investigate closed-loop vibration suppression. Simulations demonstrate improved tracking performance with auxiliary high resolution, high-rate strain sensing.
