Characterization of an ETREMA MP 50/6 Magnetostrictive Actuator
(1998)
This report presents the Displacement (Strain)-Current characteristic of an ETREMA MP 50/6 magnetostrictive actuator. This actuator is made of TERFENOL-D and displays giant magnetostriction. The displacement-current ...
On the Geometry and Dynamics of Floating Four-Bar Linkages
(1992)
In this paper, we investigate the kinematics and dynamics of floating, planar four-bar linkages. The geometry of configuration space is analyzed through the classical theory of mechanisms due to Grashof. The techniques of ...
Motion Control and Coupled Oscillators
(1995)
It is remarkable that despite the presence of large numbers of degrees of freedom, motion control problems are effectively solved in biological systems. While feedback, regulation and tracking have served us well in ...
Control Problems of Hydrodynamic Type
(1998)
It has been known for some time that the classical work of Kirchhoff, Love,and Birkhoff on rigid bodies in incompressible, irrotational flows provideseffective models for treating control problems for underwater vehicles.This ...
Adaptive Friction Compensation for Bi-Directional Low-Velocity Position Tracking
(1992)
This paper presents a comparative investigation of friction- compensating control strategies designed to improve low-velocity position tracking performance in the presence of velocity reversals for servomechanisms. The ...
