摘要

本文介绍了一种基于自感知驱动的硬盘驱动器微驱动器的控制方法。采用电桥电路的自感执行器可以测量执行器中的应变或应变的时间速率。这些传感信号对应于执行器的尖端斜率和执行器尖端斜率的时间速率。通过主动阻尼微动器的振动，实验验证了自传感驱动技术的有效性。

Control of a micro-actuator for hard disk drives using self-sensing

This paper describes control of a micro-actuator for hard disk drives using self-sensing actuation. The self-sensing actuator using electrical bridge circuit can measure either strain or time rate of strain in the actuator. These sensing signals correspond to the tip slope of the actuator and the time rate of tip slope of the actuator. The usefulness of the self-sensing actuation technique is experimentally verified by actively damping the vibration in a micro-actuator.
