A Lyapunov Functional for the Cubic Nonlinearity Activator-Inhibitor Model Equation
(1998)
The cubic nonlinearity activator-inhibitor model equation is a simpleexample of a pattern-forming system for which strong mathematical resultscan be obtained. Basic properties of solutions and the derivation ofa Lyapunov ...
A Model for a Thin Magnetostrictive Actuator
(1998)
In this paper, we propose a model for dynamic magnetostrictive hysteresisin a thin rod actuator. We derive two equations that representmagnetic and mechanical dynamic equilibrium. Our model results from an application of ...
The Hybrid Motor Prototype: Design Details and Demonstration Results
(1998)
A novel hybrid rotary motor incorporating piezoelectric and magnetostrictive actuators has been designed and demonstrated. The novelty of this motor was the creation of an electrical resonant circuit, whereby reactive power ...
Analysis of a complex activator-inhibitor equation
(1999)
Basic properties of solutions and a Lyapunov functionalare presented for a complex activator-inhibitor equation witha cubic nonlinearity.Potential applications include control of coupled-oscillator arrays(for quasi-optical ...
Computing Balanced Realizations for Nonlinear Systems
(2000)
This paper addresses the problem of computability pertaining to the Scherpen(1994) theory and procedure for balancing of nonlinear systems. In contrastto Moore's (1981) balancing method for linear systems, the Scherpen ...
H∞ Control for Impulsive Disturbances: A State-Space Solution
(1994)
In this paper we formulate and study an interesting (sub) optimal H∞ control problem related to the attenuation of impulsive disturbances to a class of linear systems. Among the motivating factors is the need to study ...
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 ...
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 ...
Efficient Implementation of Controllers for Large Scale Linear Systems via Wavelet Packet Transforms
(1998)
In this paper we present a method of efficiently implementing controllers for linear systems with large numbers of sensors and actuators. It is well known that singular value decomposition can be used to diagonalize any ...
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 ...
