Patch-type Self-sensing Actuator Using PZT and EFPI for Vibration Control

, 2004
For vibration control applications, a collocated seneor and actuator is generally desired. In addition, a self-sensing actuator is attractive from the viewpoint of instrumentation minimization.

Crone control of a nonlinear hydraulic actuator [PDF]

, 2002
The CRONE control (fractional robust control) of a hydraulic actuator whose dynamic model is nonlinear is presented. An input-output linearization under diffeomorphism and feedback is first achieved for the nominal plant.

Proof of Principle of a Rotating Actuator Based on Magnetostrictive Material with Simultaneous Vibration Amplitude

, 2020
Magnetostrictive materials are a group of smart materials with comparable properties to piezoelectric materials regarding strain and operating frequency. In contrast, the Curie temperature is much higher and the principle effect allows different actuator

Nonlinear vibrations of a stroke-saturated inertial actuator

, 2013
Proof-mass actuators are typically used to supply an external control force to a structure,for the purpose of vibration suppression. These devices comprise a proof-mass suspended in a magnetic field that is accelerated in order to provide a reaction ...
