Flux-Path Control Magnetic Suspension System Using Voice Coil Motors
Journal of System Design and Dynamics, 2007A novel magnetic suspension system with three flux-path control modules was developed. The module consists of a ferromagnetic plate, a voice coil motor (VCM) for driving the plate and a displacement sensor for detecting the position of the plate; the sensor is comprised of a V-shape plate spring and four strain gauges pasted on it.

Adaptive wavelet fuzzy CMAC system design for voice coil motors
2012 IEEE International Conference on Fuzzy Systems, 2012An adaptive wavelet fuzzy cerebellar model articulation control system is developed for the trajectory tracking control of voice coil motors (VCMs). This control system comprises a wavelet fuzzy cerebellar model articulation controller (WFCMAC) and a fuzzy compensator.

Hard Disk Drive with Voltage Driven Voice Coil Motor
2004The paper presents a novel approach for driving a Voice Coil Motor (VCM) in a Hard Disk Drive (HDD), based on an adaptive voltage driver. The adaptation of the driver compensates for the variations of VCM resistance and is performed either during seek operations and track following.
