Adaptive vibration control of hoop truss structure using voice coil actuator
International Journal of Applied Electromagnetics and Mechanics, 2016The vibration of hoop truss structure can be attenuated effectively through the voice coil actuator (VCA) under an adaptive LMS-based feedback strategy. The governing equations of the hoop truss with voice coil actuator are obtained using finite element method.

Enhanced laser shutter using a hard disk drive rotary voice-coil actuator
Review of Scientific Instruments, 2007Rotary voice-coil motors from computer hard disk drives make excellent mechanical shutters for light beams. However, the complexity of the necessary electronic driving circuit can hinder their application. A new design is presented here, using a single integrated circuit originally intended for controlling dc motors.

Research of active optics force actuator based on voice coil motor
SPIE Proceedings, 2012In order to correct the atmospheric disturbance around the main mirror and the error caused by wind, the calibration frequency must reach 10 Hz in the active optics system. Therefore, the force actuator must have good dynamic response and high-precision positioning.

Voice Coil Actuator for Active Vibration Isolation in Microgravity
2001Many microgravity experiments require very low levels of acceleration which cannot be achieved on the International Space Station due to the residual vibration. A vibration isolation system is then usually devised between the experiment and the space station to obtain the desired accelerations at the experiment level.

Voice Coil Actuator for Hydraulic Servo Valves with High Transient Performances
2006 IEEE International Conference on Automation, Quality and Testing, Robotics, 2006This paper presents a modern actuator type (voice coil actuator), based on a basic electrodynamics principle, which use Ferro fluids, for hydraulic servo valves with short transient response time. The use of Ferro fluids within the electromagnetic circuit yields an increase in the force factor, improves the damping behavior and shorten the response ...
